全装配式型钢复合墙恢复力模型研究
Research on restoring force model of fully prefabricated steel composite walls
摘要
Abstract
To research the failure mechanism and seismic behavior of fully prefabricated steel composite walls with steel castings,quasi-static tests were carried out on three steel composite walls(all the specimens had a scale of 1/2).The steel composite walls under low-period cyclic load were analyzed on damage processes,failure patterns,hysteresis characteristics,shear and deformation capacities by changing their built-in steel types and aspect ratios.Experiment results show that the steel composite walls with steel castings exhibit a typical shear failure pattern,and the steel castings are undamaged,whose performance is stable.The OpenSees software is used to simulate the specimens,and the numerical results are in good agreement with the experimental results.A two-parameter seismic damage model suitable for prefabricated steel composite wall is proposed,and the restoring force model of steel composite wall based on damage is further established.The rationality of the restoring force model is verified by comparing with the experimental hysteresis loops.关键词
