Abstract: | In Hong Kong, bridges are designed in accordance with the Structures Design Manual for Highways and Railways, issued by the Highways Department of Hong Kong Government, 1993. The methods using in bridge deck analysis are highly analytical and computer-based. Simplified methods for bridge design are allowed in various North America bridge design codes. The simplified methods are used extensively in the USA and Canada. The simplified method of analysis allows the bridge designer to determine manually the design forces in a bridge deck with a minimum calculation. At present, such simplified method is not usually adopted in bridge design in Hong Kong. This dissertation is aimed at developing a simplified method for Hong Kong bridge design code. The study has been focused on the determination of maximum live-load longitudinal moment and live-load longitudinal shear on two-lane, three-lane and four-lane bridge decks. The proposed method has taken into account some aspects of a bridge that influence its load distribution. The proposed simplified method is in a graphical form. Hand method of analysis employing formulae and charts are used to calculate the critical forces at internal and external girders. The results from the proposed method do not deviate significantly from those obtained by rigorous analysis using semi-continuum method. |
