    A K M Jahidul Alum (1992)
    This report is aimed at Investigating temperature effects on a concrete bridge deck with box-section under local climatic condition field experiments for both unsurfaced and surfaced conditions were carried to record ...
  • Development of oneway jacking system : sandjack 

    A K M Jahidul Alum (1989)
    Properly designed sand jacks can be used as one way jacks in the areas of heavy civil engineering construction works, such as bridges, massive construction works supported on temporary falseworks and adjustable formwork systems.
  • Feasibility of using global positioning system to modernize and densify the geodetic network in Singapore 

    Goh, Pong Chai; Aw, York Bin (1994)
    The Global Positioning System (GPS) is an American military satellite positioning system, with an operational plan calling for 24 GPS satellites in six separate orbital planes of 4 satellites each. The altitude is approximately ...
  • Computer-aided design for continuous prestressed concrete box-girder bridges 

    Fan, Sau Cheong (1989)
    This paper presents the concepts of using CADD technology in the preliminary design of concrete box girder bridges. The preliminary design procedure, which is traditionally a manual process based largely on the experience ...
  • Car ownership, traffic congestion and road pricing 

    Fan, Henry Shing Leung; Tan, Yan Weng (1996)
    Factors which affect private car ownership in Singapore are investigated in this study and a model for predicting demand for car ownership is developed. The model has good explanatory power with respect to variations in ...
  • Development of techniques for the analysis of aircraft movements at Changi Airport 

    Fan, Henry Shing Leung (1988)
    This report presents a suite of computer models for the analysis of aircraft movements at Singapore Changi Airport. The models come under three major categories: (1) a runway capacity model and an annual delay model for ...
  • Microwave landing system and its impact on airport capacity 

    Fan, Henry Shing Leung (1987)
    The Microwave Landing System (MLS) is scheduled to replace the existing instrument landing system as precision guidance for instrument operation by the turn of this century. This study focuses on the impact of MLS on ...
  • Use of glass fibre composite bars in prestressed concrete 

    Fan, Sau Cheong; Goh, Peng Khoon (1994)
    Composite materials has offered a new range of products to the prestressing industry. Synthetic materials such as glass, aramid and carbon fibres can be manufactured into high strength composite rods or tendons for ...
  • Evaluation of repair materials 

    Jahidul Alum; Tan, Man Hoi (1993)
    Improving the mechanical properties of existing concrete members is often difficult and costly. The use of materials not compatible with concrete, require regular maintenance, incurring additional costs.
  • Test of a variable-depth post-tensioned flat slab 

    Hurst M. K.; R. Ganeshalingam (1988)
    Nearly all the prestressed concrete flat slabs so far constructed have utilised uniform depth slabs with tendons of varying eccentricity. The behaviour and design of these slabs is well-understood and documented.
  • Automated phototriangulation of premarked targets 

    Aw, York Bin (1994)
    This report presents an attempt to automatically recognize survey targets captured on digital images using a pair of charge-coupled device cameras. Two different types of target were used, circle and rectangle. After ...
  • Applications of smart materials in health monitoring of civil infrastructures 

    Soh, Chee Kiong. (2004)
    The last few decades have witnessed the construction of vast infrastructural facilities in Singapore and other parts of the world. Now, the ageing of these structures is creating maintenance problems and increasingly ...
  • Water hammer induced problems in high-rise buildings 

    Shuy, Eng Ban. (1996)
    This study investigates the common causes of noise and vibration problems in domestic water pipeline systems, particularly those supplying high-rise buildings. The study was initiated partly in response to numerous complaints ...
  • Real-time control of activated sludge process 

    Chen, Chung-Yuan. (1988)
    A two-stage dynamic model was developed to describe the biological growth kinetics of an activated sludge system under non-steady state condition. This model is based on the assumption that there is an intermediate growth ...
  • Analysis and design of reinforced concrete deep beams 

    Guan, Ling Wei.; Kong, Fung Kew. (1994)
    Concrete deep beams, referring to beams having span-to-depth ratio of about 5, are structural members with useful applications ranging from pile caps to transfer girders in tall buildings. Deep beams have significant ...
  • Development of an intelligent CPM scheduling system for building construction management 

    Soh, Chee Kiong. (1992)
    Construction scheduling essentially entails the generation of a 'map' of operations of how the project is to be carried out. The construction schedule, or the 'map', consists of a breakdown of the project into a series of ...
  • Development of computer programs for reinforced concrete design and drafting 

    Mosley, William Henry.; Hulse, Raymond. (1986)
    The object of this project was the development of computer programs for structural design and drafting with particular reference to reinforced concrete structures. The aim was to produce programs that are well structured, ...
