基于OpenSees的方钢管混凝土柱滞回性能数值模拟
|
摘要
考虑到低周循环荷载下方钢管混凝土柱中混凝土与钢材的相互作用机理,采用Mander混凝土本构模型和Menegotto-Pinto钢材本构模型进行数值分析。前者能描述钢管对混凝土的约束作用,后者可描述钢材的随动强化和Bauschinger效应。基于开源软件OpenSees对方钢管混凝土柱P-Δ滞回曲线进行数值模拟,模拟结果与试验结果吻合较好;并就宽厚比、轴压比、材料强度进行参数分析,分析结果对方钢管混凝土结构的抗震设计具有指导意义。
Based on the interaction theory mechanism between concrete and steel inside concrete-filled rectangular steel tubular(CFRST)columns under low cycle load,a numerical analysis was carried out by using the Mander confined concrete constitutive model and Menegotto-Pinto steel constitutive model.The former can describe the constraint effect of steel to concrete;the latter can describe kinematic hardening and Bauschinger effect.Numerical simulation of hysteretic behavior of CFRST columns under cyclical loading based on OpenSees was successfully carried out.The results predicted by model were in good agreement with those of experiments.The parametric influence on hysteretic behavior was given respectively including width-thickness ratio,axial compression ratio and material strength.These conclusions would play an important role for seismic design of concrete-filled steel tubular structure.
