| 摘 要： | 应用ANSYS软件计算了钢柱在标准升温模式下的温度场,然后利用ANSYS的耦合分析模块,将温度场导入结构分析,分析了不同约束下轴心受压钢柱在温度升高时的力学反应,同时考虑了荷载比以及长细比对不同约束钢柱抗火性能的影响.研究表明:扭转约束钢柱的抗火性能要优于柱端没有扭转约束的简支柱;当钢柱长细比系数在30以内时,扭转约束...

| Abstract: | The temperature field of steel column under standard warming mode is calculated by using ANSYS program.Then the temperature field is inducted into structure analysis by using the coupling analysis module of ANSYS.The mechanical reaction of steel column with axial compress and warming under different rotational restraints is analyzed with consideration of load ratio and slenderness ratio.The research indicates that the fire-resistance performance of steel column with rotational resistance is better than that... |
