| Outline of Final Research Achievements |
The failure mode of the gusset plates demonstrated by the compression test of the steel truss bridge panel point was well consistent with that of shown by the FEM analysis. Therefore we proposed a strength equation for gusset plates subjected to the compression force through a diagonal.
In order to examine the applicability of the proposed strength equation, 3 FEM models of the panel points with different gusset shape and thickness were built, and the parametric FEM analyses were performed. As the result, the values of the load carrying capacity calculated by the proposed strength equation were well agreed with the values obtained by the FEM analyses.
