Abstract:

Hydraulic fracture is a useful technique to apply for remediation of contamination in soil and grouting during tunneling work. The effectiveness of the technique highly depend the fracture orientation and geometry. The used of hydro-fracture grouting during the tunneling is popular in construction industry. Moreover, hydraulic fracture technique is also an enhancement technology to increase formation permeability for the extraction of organic compounds from soil. In fact, the general criteria for predicting the hydraulic fracture still have not been established. The prediction of fracture orientation still heavily depends on crude empirical relationships, which are in general unable to match for complex situations in the field. The generation of excess pore water pressure during the hydraulic fracture has not been investigated. Furthermore, if the hydraulic fracture is not operating in a good controllable condition, it may cause the influence on the underground structure and superstructure, undesirable ground heave outside the target treatment zone. The proposed research aims at establishing the criteria for predicting the hydraulic fracture orientation and developing an effective fracture controlled injection technology by performing a series of laboratory tests. The main purpose of the project described herein is to develop a high efficiency fracture-controlled theory and to recommend new criteria for design and operation in different techniques. o to seek a method for predicting the soil fracture direction of single and multiple injections o to investigate the grouting behavior, the influence the hydraulic fracture on the soil properties (permeability, soil density and shear strength)

Shrinkage cracking of reinforced concrete structures

Investigator(s):

Au FTK

Department:

Source(s) of Funding:

Small Project Funding

Start Date:

09/2005

 

Abstract:

Shrinkage of a concrete structure as the concrete dries after hardening is a natural phenomenon. It could lead to substantial shortening movement and, if the movement is restrained, serious cracking of the concrete structure. This is a common problem in Hong Kong, especially in large podium structures with several tower blocks on top. In many cases, the shrinkage cracks formed have been causing aesthetic, water leakage and durability problems. In a recently completed applied research project funded by the Hong Kong Housing Authority Research Fund (HARF) that comprises experimental work and development of application software, apart from addressing most of the problems, many interesting issues have also been identified.The cracking of reinforced concrete is a very complicated phenomenon as it involves the interaction between concrete and steel reinforcement, the shape and size of the structure as well as the stiffness of the supports. It is against this background that the present project is proposed and the objectives are:1. To carry out some pilot tests to investigate the mechanism of shrinkage cracking; and 2. To develop an efficient computational method for the analysis of shrinkage movement and strain.

Abstract:

(1) To conduct appropriate analyses (principally nonlinear static e.g. pushover, modified to account for higher modes in tall buildings) to establish the full-range capacity and associated fragility curves of the principal building categories found in Hong Kong. The specific focus will be on the displacement monitoring of these building forms in response to lateral loadings, such as the identification of soft storeys, and so on, and its extension to damage assessment and monitoring. (2) To facilitate the above assessment, a detailed database of building information (structural system, height, age, irregularities, site condition, etc) will be compiled for three selected study regions. Statistical analyses of the data will be conducted, to determine the distributions of building types and hence infer the characteristics of the building stock of Hong Kong as a whole. From this, buildings will be categorized, based on expected seismic performance capabilities. (3) To integrate the buildings database, fragility/capacity curves and seismic hazard estimates of previous RGC-supported studies (for rock and various typical soil sites) to determine the risk of various defined levels of damage due to earthquakes associated with a range of PE. To conduct sensitivity analyses to determine the variability of such predictions based on the degree of reliability of the input data.

Abstract:

The increased anthropogenic effects on the natural surroundings (Lean and Warrilow 1989) require a physical-based numerical model system urgently for understanding and predicting potential consequences caused by such effects. Meanwhile, the improved capability in modelling land-surface hydrologic processes (Sellers et al 1997) makes it possible to use a physical-based system to evaluate the availability of the water resources and to study the sustainability of the environment. However, the limitation of our understanding in the hydrologic cycle still is the major obstacle to advancing the model representation and to applying the model prediction, which can guide our regulations in mitigating the natural hazards. For relaxing this limitation, the objectives of the project are planned as follows: 1. To identify the sensitivity of different land surface processes in a coupled land-atmosphere numerical model system, 2. To integrate achievable new understandings of hydrological processes into the land surface parameterization in the coupled model system, and 3. To evaluate the improvement of land surface performance in the system (see Reference at the end of Section VII)

Start Date:

Abstract:

- Objectives: (1) To characterize the types and concentration of the disinfection by-product (DBP) precursor material in wastewater effluents of various degrees of treatment and the resulting DBP types and abundance in finished drinking water; (2) To investigate the stability, transformation and the change in the DBP formation characteristic of the wastewater DBP precursors in the surface water environment undergoing biodegradation and sedimentation. - Key issues and problems: Due to the worldwide decline of water resources, treated wastewater has become a growing portion of water supplies. Many surface water bodies, i.e. rivers, lakes and reservoirs, are used for both wastewater disposal and fresh water withdrawal for drinking water. The percentage of treated wastewater in drinking water sources could be as high as 100% in some cases during the drought season. However, little is known about the impact of wastewater discharge into the water resources on the DBP formation in finished drinking water. The wastewater-derived DBP problem can be much more serious in developing countries due to the lack of wastewater treatment and water environment protection. For example, along with the rapid economic development in China in the past two decades, more than 80% surface water resources are polluted to various extents by sewage disposal, including the East River in Guangdong that provides more than 70% fresh water supply of Hong Kong. Deterioration in the source water quality greatly impairs the capability of conventional water treatment, especially for DBP control and minimization. Natural organic matter (NOM) in surface water has been considered as the predominant DBP precursor (Singer 1999; Xie 2004). Numerous studies have been conducted on the characteristics, reactivity and DBP yield of NOM in chlorinated drinking water. However, there is little information about the DBP precursors brought about by wastewater discharge. Organic impurities that are present at higher concentrations in wastewater effluent than in natural waters would make a considerable contribution to DBP formation in drinking water (Galapate et al. 1997; Rostad et al. 2000; Chu et al. 2002). Wastewater precursors with chemical features different from NOM may lead to the formation of different DBPs than those typically formed in drinking water systems. On the other hand, natural reactions and processes, such as biodegradation and sedimentation, would affect the stability and transformation of the wastewater DBP precursors in the receiving water, altering their reactivity with chlorine in DBP formation. These wastewater-derived drinking water DBP issues remain to be addressed through experimental investigations. .

Abstract:

The finite element method is now a well established tool for the analysis of complicated engineering structures of irregular geometry, such as tall buildings, bridges, automobiles and aircraft, etc. However, this versatile technique gives only an approximation solution whose accuracy depends on the number of elements and the sophistication of individual elements used in the finite element model. With the introduction of the adaptive refinement procedure, the goal of achieving economically reliable finite element solution of specified accuracy for general three-dimensional problems is possible and feasible. Many high-performance solid elements of various geometrical shapes and orders have recently been developed based on the hybrid stress approach and the weak continuity requirement between elements. Parallel to this development are advances in the automatic mesh generation techniques over curved surfaces and within three-dimensional volumes [1-5]. A research project is proposed to bring the latest advances in solid element technology and the mesh generation techniques together to form an integrated adaptive refinement analysis scheme for providing high-quality economical solutions to practical engineering and benchmark problems, which cannot be obtained otherwise by classical simplified models of reduced dimensions.

The aim of this study is to establish a reliable and practical model for evaluating the concession items put forth by the consortia in a Public-Private Partnerships (PPP) scheme so as to attain a "win-win-win" situation amongst the public bodies, private organisations, and end-users. The objectives of this study include:i) identifying the Critical Success Factors (CSF) for PPP projects and their impacts on concession evaluation;ii) examining the current practice being used for evaluating the concession items; iii) devising a fuzzy evaluation model to establish the impacts brought by concession items initiated by bidders; andiv) validating the fuzzy concession evaluation models using synthesized and real data. There is a growing awareness of the benefits seeking private organizations' involvement in providing and operating public facilities and services. Public Private Partnerships (PPPs) constitute an emerging approach that utilizes the financial, technical, managerial and commercial strengths of private enterprises to deliver public facilities/services which would otherwise be difficult to provide (Akintola et al, 2003). Through PPP, private partners would have a greater incentive to identify and adopt innovative approaches in providing and/or operating the facilities, and this could result in cost saving and an improvement in service quality (Smith, 1999; Chege and Rwelamila, 2001). With a shortage in public funding, there is a growing pressure for the public agents in Hong Kong to adopt the PPP concept (cf: Angeles and Walker, 2000), and examples of these including the much debated West Kowloon Cultural District, High Speed Road Maintenance Project, etc. While there are established mechanisms to measure the performance of private partners and regulate the tariff/charge during the operation stage, they are usually protected by an assured revenue stream (especially those working under the concession-based PPP) meaning that they can raise the tariff/charge should their revenues fall below the desired level of return (Merna and Smith, 1996). As a consequence, awarding a PPP project to one who proposes a very low tariff might sound attractive at start, but may eventually result in public discontentment and political upheaval should there be an incessant increase in tariff/charge like what is happening with the Western Harbour Crossing in Hong Kong. A major review on the literature and the technical circulars of the HKSAR Government reveal that there is a lack of informed approaches in evaluating PPP concessions. There is a need to establish a reliable yet practical strategy for evaluating concession items, viz. the (i) ideal concession or operating period; (ii) relationship between the tariff/charge and expected return; and (iii) stability of tariff/charge. However, to evaluate a PPP concession is never an easy task as decision-makers have to rely on a number of vague assumptions and the results may also be affected by the risks and uncertainties during the development and operation stages. Potential risk factors affecting the revenue include (i) cost overrun triggered by inflation, technical or managerial shortfalls, climate or environment change, and other such factors; or underestimation of revenue due to shrinkage in demand, recession, increased competition, etc, which are difficult if not impossible to quantify at the concession evaluation stage. When evaluating the concession items, risks and uncertainties must be duly considered. In this study, a concession evaluation model will be developed based on the fuzzy sets approach to improve the reliability and efficiency of this kind of decisions.

Abstract:

A large number of civil infrastructures and buildings around the world are in a state of serious deterioration due to weathering and aging. Moreover, many structures are no longer considered safe due to increased-load specifications in the design codes. In Japan, the vehicle load designed for highway bridges has recently been increased by 25%. Similar situation has occurred in European Union countries, as currently all the major roads and associated structures are required to be upgraded to carry up to 40 tons total axle load which may overload many existing bridges that were built over the last 40 years. In Hong Kong, new seismic code is expected to in forced in year 2010, new loading provisions would be imposed to existing buildings. These new load requirements have put the safety and integrity of many existing structures in question. Reinforced concrete (RC) material is not good in recycling, to reuse the structures and to protect the environment, substantial strengthening, retrofitting, refurbishment or rehabilitation of different structural components are required. Strengthening of existing concrete structures by using bolted external steel plate has recently been attracted much attention [1-4]. The behaviours of the bolt groups that play a key role in the strengthening works need to be thoughtfully studied. In this proposal, the full range of linear and non-linear responses of bolt groups is to be determined by experimental study and numerical simulation. New theory based on varying the position of the point of rotation of the bolt group and hence the bolt forces to balance the applied loads is proposed. New computer program would be developed to verify the theory. Experiments would be conducted to measure the non-linear load-slip relationship of single bolts. Owing to the versatility of the proposed theory, it could cater for different stiffness, load-slip relationships of bolts as well as various loading conditions. The theory is expected to widely use in many different strengthening works.

Abstract:

It is now well recognized that road safety is a public health problem. Road safety was the theme of World Health Day 2004, on which hundreds of organizations around the globe hosted events to help raise awareness about road traffic injuries, their grave consequences, and enormous costs to society. This addresses the fact that road traffic accidents are among the eight leading causes of death worldwide. Each year, around one million people die in traffic accidents. In Hong Kong, a major traffic incident involving a container truck and a double-decked bus occurred on 10 July 2003 on Tuen Mun Road, resulting 21 fatalities and 20 injuries. In response to this incident, the Chief Executive appointed an Independent Expert Panel, of which the investigator was one of the three members, to examine and make recommendations on road safety measures for improving road safety. This has led to a publication of the “Report on Enhancement of Highway Safety”, in which a number of road safety measures were proposed. Many of these measures are currently being seriously considered, and will be put on trial or implemented soon. In addition to these measures that are mainly for high speed highways, other road safety measures in urban environment have also been implemented in the past few years or will be implemented in the distant future. It is essential to develop a methodology that can help evaluate the effectiveness of these road safety measures in reducing road traffic accidents and casualties. This project aims to develop an observational before-and-after study methodology to evaluate the safety performance of road safety measures, and use the road safety schemes that will be implemented in Hong Kong as case studies to demonstrate the usefulness of this methodology and more importantly the effectiveness of these schemes in reducing traffic accidents and casualties.

Project Title:

Laboratory study on the feasibility of using the foundation system as a heat exchanger for the water-cooled air conditioning system

Investigator(s):

Department:

Civil Engineering

Source(s) of Funding:

Start Date:

Abstract:

Lower energy expenses can significantly lower the business costs of Hong Kong, rendering Hong Kong more competitive economically in the world market. Moreover, reduction of electric power consumption can contribute significantly to the sustainable development of Hong Kong. The electric power consumed by air conditioning systems in Hong Kong accounts for about one-third of the total electric power consumption. With an increasing population and continuing development, the use of air conditioning is growing in the years to come. It is recognized that prudent means for improving the energy efficiency of air conditioning systems may lead to substantial reduction of electric energy consumption, thereby resulting in overall economic as well as environmental benefits to the society. Studies conducted by the Electrical and Mechanical Services Department of the Government confirm that one of such means is wider implementation of the water-cooled air conditioning system (WACS) which uses cooling water to remove heat from the condenser unit because: (1) WACS is more energy efficiency than the air-cooled system; and (2) reduction of electricity consumption leads to lower emission of combustion products from the electricity generation process. For the time being, the ultimate receiving body for the effluent of WACS in Hong Kong is the sea. Therefore, commercial, industrial or institutional buildings using large WACSs need a continuous supply of cooling water and a convenient heat sink for heat transfer. For wider implementation of the WACS, these two problems must be solved. Many tall buildings in Hong Kong are supported by large-diameter bored piles of typical lengths of 40 m to 100 m. During the construction of bored piles, at least four tubes are built for each pile along the full length of the pile for performance of sonic tests to evaluate the integrity of the constructed pile. It may be possible to circulate cooling water of the WACS through these tubes so that heat can be transfer to the Earth at no extra construction costs. This research program is proposed to establish the viability of using the Earth as the heat sink for the WACS in lieu of the sea by laboratory measurements and computer simulations.

Behaviour of Cold-formed High Strength Steel Beams

Investigator(s):

Young B

Department:

Civil Engineering

Source(s) of Funding:

Seed Funding Programme for Basic Research

Start Date:

06/2005

 

Abstract:

Cold-formed steel structural members may lead to more economic design than hot-rolled steel members as a result of their superior strength to weight ratio and ease of construction. Cold-formed steel beams are used increasingly in light gauge construction. The use of high strength material could improve the load carrying capacity of the structural members. Therefore, cold-formed steel beams fabricated from high strength material would lead to cost saving. The existing "Hong Kong Code of Practice for the Structural Use of Steel (Limit State Approach)" is limited to steel grade of 450 MPa. The Hong Kong Steel Code does not cover high strength material of yield stress greater than 450 MPa. Furthermore, high strength material is not as ductile as normal strength material. Hence, there is a need to investigate high strength steel material. Web crippling is a form of localized buckling that occurs at points of concentrated loads or supports of structural beams. Cold-formed steel beams that are unstiffened against this type of loading could cause structural failure by web crippling. Transverse stiffeners can be used to prevent the structural failure. However, transverse stiffeners are often difficult and uneconomical to install on structural steel beams. The purpose of this research is to investigate the behaviour of cold-formed high strength steel beams. A series of tests will be carried out on cold-formed high strength steel beams subjected to web crippling. A non-linear finite element model will be developed based on the test results. The experimental and theoretical investigation would provide a better understanding of the behaviour of cold-formed high strength steel beams subjected to web crippling. Hence, design rules for cold-formed high strength steel beams will be proposed. These design rules can be used locally in Hong Kong as well as internationally. In summary, the key issues and problems are as follows: o Cold-formed steel structural members may lead to more economic design than the conventional hot-rolled steel members. o The use of high strength material could improve the load carrying capacity of the structural members. o The existing Hong Kong Steel Code does not cover high strength material (Yield stress greater than 450 MPa). o Cold-formed steel beams that are unstiffened against concentrated loads could cause structural failure by web crippling. o Transverse stiffeners are often difficult and uneconomical to install on structural steel beams. The objectives of the project are as follows: o Conduct a series of tests on cold-formed high strength steel beams subjected to web crippling. o Develop a non-linear finite element model based on the test results. o Perform an extensive parametric study of cross-section geometry using the developed finite element model. o Enhance the understanding of the behaviour of cold-formed high strength steel beams. o Compare the experimental results with the design strengths obtained using the Hong Kong, American and Australian/New Zealand design specifications. o Investigate the appropriateness of the current web crippling design rules for high strength steel material. o Propose web crippling equation for cold-formed high strength steel beams.

Department:

Start Date:

06/2006

 

Abstract:

The use of cold-formed steel structural members has increased rapidly in recent years, especially in cold-formed steel construction, such as steel-framed housing, office buildings, factories and warehouses. Cold-formed steel can be used efficiently in many applications where conventional hot-rolled steel members prove to be uneconomic. However, traditional cold-formed steel sections, such as channel, Zee and angle sections have been well investigated. Therefore, a new type of innovative cold-formed steel sections are needed, where the new sections will be structurally more efficient and econmical than the traditional cold-formed steel sections.The purpose of this research is to develop a new type of innovative cold-formed steel sections through both experimental and theoretical investigations. New design rules for the innovative cold-formed steel sections will be proposed. The new innovative cold-formed steel sections can be used in Hong Kong as well as elsewhere.The objectives of the project are as follows:o Develop a new type of innovative cold-formed steel sections.o Use numerical analysis to design the innovative cold-formed steel sections.o Perform experiments on the innovative sections to assess the structural performance of the sections.o Develop a nonlinear finite element model (FEM) based on the test results.o Perform an extensive parametric study using the developed FEM. Hence, more results can be obtained from the parametric study.o Propose design rules for the innovative cold-formed steel sections based on the experimental and numerical results.

Abstract:

To investigate the microbial community in the activated sludge treating Hong Kong's saline sewage. Hong Kong is leading the world in treating saline sewage, which results from the fresh water conservation by large scale seawater toilet flushing. Several secondary municipal sewage treatment plants in Hong Kong successfully treat a total of about 200,000 m3 saline sewage (containing 6000 mg-Cl-/l as the average) daily to produce effluents in compliance with the discharge standards. It is thus of great scientific and engineering importance to understand the diversity and characteristics of the halophilic (salt tolerant) microorganisms in such activated sludge, and yet very little related information is available. Results of this study shall provide valuable information that will be needed to further improve the effluent quality of Hong Kong's sewage treatment facilities. Such information will also benefit other cities that are planning to follow Hong Kong's practice of using seawater for municipal purpose. To isolate and characterize the dominant halophilic bacterial species in activated sludge treating Hong Kong's saline sewage. The dominant halophilic microorganisms treating saline sewage differ from those treating fresh water sewage. To isolate and characterize these halophilic bacteria will not only produce scientific information which may lead to improving the performance of Hong Kong's treatment facilities, but also provide useful knowledge for other cities worldwide which are planning to follow Hong Kong's practice. To design DNA probes/primers specific for the identified halophilic bacteria. DNA probes and primers used in hybridization and PCR (polymerase chain reaction) have been increasingly applied to wastewater treatment and study. New DNA probes/primers are needed for the halophilic bacteria treating saline sewage, since probes/primers presently available for bacteria treating freshwater sewage are unlikely applicable. The DNA probes developed in this project will be valuable tools for the study and control of saline sewage treatment.
