摘要
应用有限元分析软件OpenSEES,基于纤维模型法和柔度法,通过选择适宜的单轴材料本构模型,建立起十字形钢混凝土柱的有限元分析模型,并对试件进行低周往复荷载作用下的非线性数值模拟。结果表明:所建立的OpenSEES模型能很好的反映十字形钢混凝土柱滞回环的特点,此次模拟的结果可为十字形钢混凝土结构数值模拟和地震反应分析提供参考。
Application of finite element analysis software OpenSEES,based on fiber model method and flexibility method,by choosing appropriate uniaxial material constitutive model,this paper established finite element analysis model of cross steel reinforced concrete column,and made nonlinear numerical simulation to specimens under low reciprocating load.The results showed that： the established OpenSEES model could well reflect the characteristics of cross steel reinforced concrete hysteresis ring.The simulation results could provided reference for the numerical simulation and seismic response of steel concrete structure.
