| 摘 要： | 通过双重非线性有限元程序ANSYS5.7,分析了不同轴压比对人字形支撑和X形支撑的两种巨型钢柱滞回性能的影响规律。并针对地震作用下实际结构中巨型柱可能出现的受力状态,讨论了轴力和水平剪力同时增加或减小时巨型钢柱的滞回特性。

| Abstract: | Using dual non-linearity FEM program ANSYS5.7,the hysteretic behaviors of mega steel columns braced with inversed V bracings and X bracings are studied under the action of different axial compression ratios.The hysteretic behaviors are also studied when the axial force and shear force are increased or decreased with the same ratio,which ofte occurred in the seismic loading conditions. |
