考虑约束混凝土本构的压扭钢骨混凝土柱非线性受力分析
|
摘要
为研究考虑约束混凝土本构压扭钢骨混凝土柱的抗震性能,预先通过有限元分析软件ABAQUS建立承受压扭钢骨混凝土柱构件的有限元模型,对柱试件进行水平循环加载数值模拟,以轴压比、扭矩和含钢量为试验变量,分别从滞回曲线、骨架曲线、耗能性能、延性及刚度退化方面进行分析,研究压扭型钢混凝土柱构件的抗震性能,为复合受扭试验研究奠定基础。
In order to study the seismic performance of restrained concrete compressive-torsional steel reinforced concrete columns,the finite element model of steel reinforced concrete columns subjected to compressive and torsional loads is established by finite element analysis software ABAQUS in advance.The horizontal cyclic loading numerical simulation of the column specimens is carried out. The experimental variables are axial compression ratio,torque and steel content. The hysteresis curve,skeleton curve,energy dissipation performance,ductility and stiffness degradation are analyzed. The seismic performance of compression-torsion steel reinforced concrete column members is studied,which lays a foundation for the next composite torsion test.
