| 摘 要： | 对巨型框架-耗能支撑结构新体系进行了罕遇地震作用下的弹塑性时程分析,研究该体系的减震性能和耗能支撑的不同布置方式对结构的减震效果。结果表明:如果耗能支撑布置位置得当,可以用较少的耗能支撑个数达到较好的减震效果;巨型框架-耗能支撑结构不但可以减少原巨型框架-支撑结构的层间侧移,还可以减少其底部剪力和顶层加速度反应的峰值。

| Abstract: | Inelastic time history analysis was carried out for mega frame with energy-dissipating braces system under rare earthquake.The damping performance of the new system was studied,and the mitigation effect of differently arranged energy-dissipating braces was also studied.Analysis shows that if the energy-dissipating braces are properly arranged,a signficant mitigation effect can be produced by a few energy-dissipating braces;as compared to the mega braced frame structure,the mega frame with energy-dissipating braces can reduce not only the inter-story displacement,but also the base shear and the peak acceleration response of the top floor. |
