The limit state of members, the clarification of the limit state and its quantitative evaluation are issues.
In this study, an analytical study is carried out on a three-point bending test of a composite two-main girder specimen with a deteriorated RC slab of 1/2 scale, which was conducted as a study contributing to grasping the limit state as a structural system.
Although the analysis model did not take into account the damage to the RC slab, the results of the experiment and the analysis generally agreed with each other, confirming the validity of the FEA conducted. It is necessary to pay attention to the fact that there is a reproduction analysis.
