FEA on one-story single-bay self-centering steel plate shear walls
摘要
Abstract
The self-centering steel plate shear wall (SC-SPSW) combines post-tensioned (PT) frame with thin steel plate shear walls.The infilled web plates are used to provide lateral-resisting stiffness and energy dissipation of the system,whereas PT beam-to-column connections provide self-centering capabilities.Numerical models including the two-story single-span and one-story single-span SC-SPSWs were built based on ABAQUS software platform,in which the web plates were simulated using shell elements.By comparing the simulation numerical responses with the experimental results of the two-story single-span SC-SPSW model,the effectiveness of the modeling method has been verified.Then parametric study was conducted on a number of one-story single-span SC-SPSWs with changing length and thickness of web plate.The results including the responses of SC-SPSW general hysteresis,self-centering capabilities,web plate mechanical properties and structural base shear force were analyzed,especially the stress distribution and development in the tension-field of web plate were investigated.With the larger web plate length and thickness,the compression strength of web plate is increased,the negative influence of web plate on the structural selfcentering capability is more obvious.For one-story single-span SC-SPSW,the effect of web plate length on the shear force resisted by PT frame is negligible and the structural base shear force is in direct proportion to the length and thickness of web plate.The results show that the modeling method can be applied to simulate stress distribution behavior of web plate in SC-SPSW accurately,and used to the modeling of SC-SPSW with web plates of complex configurations.关键词
