为了解巨型钢框架-拉索支撑体系在水平荷载作用下的破坏性能，采用倒三角和均匀分布两种水平加载模式对经抗风抗震优化后的巨型钢框架-拉索支撑结构进行Pushover分析，研究在不同水平加载模式下的出铰顺序，并考察其抗侧刚度及拉索受力特征。研究表明，在倒三角和均匀分布两种加载模式下，结构的出铰顺序基本一致，构件破坏先后顺序为巨型柱肢间支撑、巨型梁腹杆、楼层梁、柱肢。均布加载得到的抗侧刚度大于倒三角分布；拉索退出工作的时间越早，则同一层中另一侧索拉力增加得越快。

The Pushover analysis is applied to investigate the failure mode and anti-seismic performance of the mega steel frame and cable bracing structure system under two different lateral loading patterns :the inverted tri-angular and uniform distribution .The developing sequence of plastic hinges , lateral stiffness , and characteristics of pre-stressed cables in a typical mega steel frame and cable bracing structure with optimized member sections are researched .The results indicate that the developing sequences of plastic hinges under these two lateral load -ing patterns are the same .The failure sequence of members is: braces between columns , web rods of mega beams, floor beams, and columns.The lateral stiffness under the uniform loading is larger than that under the inverted triangular loading .The earlier the cable fails , the more rapidly the tension of the other cable in the same story increases .
