【摘要】 对3根高强钢管混凝土短柱的承载力进行了轴压试验,绘出了它们的荷载—应变曲线;同钢管以及混凝土柱相比,其承载力有较大幅度提高。另外,利用有限元软件ANSYS对高强钢管混凝土短柱轴压试验的全过程进行了数值模拟,得出的荷载—应变曲线与试验曲线相比吻合较好。更多还原

【Abstract】 Based on the axial compression-loading experiment results of three high-strength steel tube-confined concrete short columns, their loading-strain curves are plotted. The load bearing capacity of steel tube-confined concrete short column is higher than steel tube or concrete. High-strength steel tube-confined concrete short columns under axial loading are analyzed by using finite element software ANSYS and their loading-strain curves are obtained. These curves agree with experimental curves.更多还原
