A steel railway through-truss bridge with SRC slab has advantages on the reduction of the slab height and so on. The fact that the main trusses restrict the SRC slab makes difficult to verify the behaviors of the slab. The authors conduct pull-load and dry-shrinkage experiments by using model slabs and apply these results to the designs of three-span continuous steel through-truss bridges.
In this study, the authors demonstrate the behaviors of the lower chord members, cross girders, slabs and so on by measuring stress and strain of each member of these truss-bridges and analyzing them by considering the cracks of the SRC slabs. Based upon these results, the authors also propose simple and practical design methods of the SRC slabs.
