Abstract:
The works on the performance behavior of staggered truss system of steel structure under severe earthquake were studied. Through using the modified nonlinear static procedure(NSP)method, an engineering example using staggered truss system and a modified proposal based on the original design scheme were fully investigated. The failure mode and ductility requirement of the two proposals under severe earthquake were presented in detail, and the characteristics of failure mode and ductility requirement of interfloor displacement of the two proposals under severe earthquake were also gained. The analysis results indicate that plastic hinges mostly concentrate on truss web member, and there is no plastic hinge in column, that the deformability of staggered truss system which has good earthquake resistance capability and ductility under severe earthquake is good and stiffness degradation is obscure.
