摘要
利用ABAQUS有限元软件对再生混凝土纯扭构件进行仿真模拟试验。模型采用修正的再生混凝土本构关系模型以及混凝土塑性损伤模型可以较好地模拟再生混凝土纯扭构件的受力状态。将模拟计算结果与试验实测结果进行对比分析表明,试件极限阶段的混凝土和钢筋应变、极限阶段的承载力、荷载-变形滞回曲线的模拟值与实测值均吻合较好。研究内容为进一步丰富再生混凝土结构的抗震性能研究提供了理论支撑。
The recycled aggregate concrete torsional members are analyzed and simulated by using the finite element software ABAQUS.Modified constitutive model of recycled aggregate concrete and plastic damage model are used for simulated the stress of the torsional members.The simulated results agree well with the test ores in stress,ultimate capacity and hysteresis curves.The research content of this paper provides theoretical support for the research of seismic behavior of recycled aggregate concrete.
