鋼トラス橋の冗長性に関する数値的検討

Numerical Consideration on Redundancy of Steel Truss Bridgess Particles

高橋 岳太 (Gakuta TAKAHASHI)

Since collapse of Mississippi river bridge in 2007, redundancy has become of importance as one of the performance of bridges. However, enough research on the redundancy has not been conducted because the redundancy has not been regarded as primary capability of structures so far. Consequently, focusing on floor slabs and gusset plates, we numerically examine their contribution to the redundancy of steel truss bridges by a series of nonlinear finite element analyses.
