| 摘 要： | 应用大型有限元分析软件ANSYS对高温作用下的高强混凝土轴心受压柱(C60)进行了仿真模拟,研究了轴压柱在不均匀温度场下的温度分布,并采用先升温后加载的顺序单向耦合法,对轴压柱的高温力学性能进行了理论分析,给出了柱荷载-挠度全过程曲线,通过与试验结果的对比表明,采用本文方法进行高强混凝土柱抗火性能的分析是可行的.

| Abstract: | The simulated experiment is done with high-strength concrete(HSC) axial compression column at high temperature.Using FEA program ANSYS,the temperature distribution of the section at non-uniform temperature field is analyzed.At the same time,through the way to elevate the temperature first and load at last,a theoretical study is made on the mechanical properties at high temperature and the load-deformation curve of HSC axial compression column is compiled.The calculation and the test results show that the proposed method is proven workable to the analysis on fire-resistance behavior of HSC construction. |

| Keywords: | reiforced concrete columns axial compression column load-deformation curve fire-resistant property |
