The Structures Design Manual for Highways and Railways (SDM) recommends that the composite bridges in Hong Kong shall be designed in accordance with the requirements of BS 5400: Part 5. The methods adopted in such analysis are usually highly analytical and computer based. On the other hand, simplified methods for composite bridge designs have been widely used overseas and yet such methods have not been applied very much in Hong Kong. The use of simplified methods will not only shorten the time spent on analysis, but will also permit the designer to retain a "feel" of behaviour of the bridge which is usually lost in traditional analyses. Previous reports have demonstrate its application to composite slab-on-girder bridges with two lanes in Hong Kong. This paper is aimed at developing a simplified method for composite bridges with more than two lanes. The proposed method has taken into account some aspects of a bridge that influence its load distribution. The proposed method is in a graphical form. Manual calculations 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 other rigorous bridge deck analyses. The calculated design forces for the girders could then be used for further steel design.
Impact and interest:
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
