摘要
基于ANSYS有限元平台,通过考虑材料非线性及相关几何参数,建立钢板笼混凝土短柱的三维有限元数值模型,分析不同配箍特征值下钢板笼混凝土短柱的荷载位移曲线,以及核心混凝土受压强度.结果表明:所建立的钢板笼混凝土短柱轴压有限元数值模拟分析模型是可行的,与试验结果基本吻合.
Based on ANSYS finite element software, considering the material nonlinearity and geometric parameters, the numerical model of concrete short columns with prefabricated cage three-dimensional finite element numerical was established to analyze the short column load-displacement curve under the different stirrup characteristic values, and core concrete compressive strength. It is shown that the finite element model of the prefabricated cage system concrete short columns under axial compression is valid, the numerical simulation results conform with the experimental results.
