Abstract:
Static behavior of partially overlapped square hollow section(SHS)KK-joints was studied by finite element analysis software ANSYS involved in large deflection elastic-plastic range. The ultimate bearing capacity and the plasticity area spread process of the overlapped KK-joints under loading were investigated and the joint failure mechanisms and failure modes were revealed. The ultimate bearing capacity of the KK-joints and its variation regularity with geometric parameters were obtained. Two loading conditions were taken into account in analysis which revealed that ultimate bearing capacity of joints and the effect of main geometric parameters on joints' static behavior were almost same to most joints. The results show that the strength equation of partially overlapped SHS KK-joints covering the effect of main geometric parameters is developed through the multiple linear regression analysis based on the results of finite element analysis. The equation is founded to provide strength predictions to a very high degree of accuracy by comparing with the results of finite element analysis. It can be used in structural design as a reference.
