基于OpenSees的双钢板混凝土组合剪力墙数值模拟
Numerical Simulation of Double Skin Composite Wall Based on OpenSees
摘要
Abstract
In order to simulate the cyclic behavior of double skin composite wall(DSCW)under earthquake excitations,a uniaxial material model,named CFSTsteel,that could capture the local buckling effect and fracture of steel plate was proposed.This model can implicitly simulate the cyclic hardening and softening of steel plate under cyclic loading,which exhibit path-dependent characteristics due to local buckling.Based on the OpenSees software,the fiber model of DSCW was established.The proposed fiber model of DSCW was employed to predict the cyclic behavior of DSCW specimens under maximum considered earthquake loading protocol.The simulate results showed that,compared to the traditional uniaxial material model Steel02,which does not consider cyclic deterioration,the predicted results using CFSTsteel could more accurately capture the cyclic deterioration of stiffness and strength of DSCW under cyclic loads.The proposed uniaxial material model has been implemented in the Open System for Earthquake Engineering Simulation(OpenSees)platform.关键词
