Abstract
Benefit from LSD introduction is apparent for the design of steel-concrete composite girder bridges. In order to establish LSD, one of issues is to get a correct evaluation of ultimate strength in plastic region. So far, such evaluating formulae have been presented mainly from EC and AASHTO LRED. However, unresolved subjects to be improved or clarified have been seen, hence, several of them were clarified in this study based on experiment. Composite test girders were subjected to sagging or hogging flexure. Ultimate flexure strength of the girder under sagging flexure, in which plastic neutral axis is positioned in the slab, was examined. Ultimate coupled flexure/shear strength was also examined. Finally, the design procedure related to this study was summarized.
