Abstract: In this paper, based on the test results of the perspex model bridges and the analysis of the transverse load distribution for wide and shallow curved slab bridges, comments on several kinds of current practical methods for calculating curved multi-girder bridges are given. In the meantime, a comparison between the structural behaviours of the bridges either with or without a middle diaphragm is made. Many data in this paper may be used for selecting the structural type and the calculation method in bridge design.

Key words: curved slab bridge with multi-cell section, transverse distribution of load, stiff diaphragm method, hinge-junctioned plate method, orthotropic plate simulation method, coupled action of bending with torsion, outside arc, inside arc
