Abstract

A joint of truss bridges which connects main structural members is the critical part of the structure system. For the collapse of I-35W bridge in the United States in 2007, the collapse was proceeded from the failure of the gusset plates in the joint which was subjected to compressive force through the diagonal member. After this incident, the method to evaluate the capacity of gusset plates subjected to compressive force has been investigated in the research field. This study focuses on the pre-proposed strength equation of gusset plates subjected to compressive force, and examines the applicability of the strength equation by FEM analyses of multiple joint models which are created on the basis of the real joints in the former Choshi Bridge.
