Nowadays, severe damage on the gusset plate connection of steel truss bridges due to corrosion has been widely reported all over the world. In this context, the remaining load-carrying capacity of a corroded gusset plate connection was evaluated by using the loading test and Finite Element Method (FEM) analysis. Two potential forms of corrosion on the gusset plate, namely welding and cross-sectional corrosion, were proposed to investigate the reduction of load-carrying capacity. The overall FEM model dimension for the real bridge was scaled down by a percentage of 50%. The degrees of corrosion sections were assumed disconnected at about 50% of the weld length and the loss of the gusset plate thickness was 50% and 75%. Parametric FEM analysis was performed to evaluate the effect of the degree of corrosion on the remaining load-carrying capacity of the gusset plate connection. |
