摘要
采用双重非线性有限元程序ANSYS5.7,分析了不同加载方式、轴向荷载、支撑长细比、支撑轴向刚度和横梁刚度等因素对人字形和X形支撑的巨型钢柱滞回性能的影响规律。为巨型钢框架结构中巨型钢柱的设计提供了理论依据和合理建议。
Using dual non-linearity FEM program ANASYSS. 7, the hysteretic behaviors of mega steel columns braced with inversed V shape bracings and X shape bracings are studied with some influencing factors, including loading modes, axial compression ratios, slenderness ratios of braces, axial stiffness of braces, and stiffness of beams. Based on the research results, the theoretical basis and some reasonable suggestions are put forward in the engineering design of mega steel frames.
