In order to propose a design and load-bearing checking method using finite element analysis, grid analysis and FEA for a steel I-girder multi-girder bridge have been carried out, and a basic study on response extraction has been conducted. In this paper, following the previous reports, the effects of horizontal stiffeners on steel girders and the points to be considered for stress evaluation on fulcrums were discussed.
