［摘要］同济大学教学科研综合楼在地震作用下结构呈现明显的扭转不规则特性，需设置必要的柱间支撑体系来控制扭转效应。采用非线性时程分析和弹塑性静力分析，对钢支撑和粘滞阻尼支撑两类支撑的连续与非连续布置共四种支撑方案进行对比分析。结果表明，连续支撑布置比非连续支撑布置具有更优的抗震性能和抗扭性能，尤其是连续阻尼支撑布置，但与建筑立意不协调。非连续钢支撑布置时层刚度不规则，不利于减小地震反应和控制结构扭转。非连续粘滞阻尼支撑布置克服了非连续钢支撑布置存在的不足，保证结构具有足够的抗震、抗扭性能，且能使得结构布置与建筑相协调。

Abstract:This structure represents obvious torsion effect when earthquakes occur and it should adopt proper column and brace system. Nonlinear time history analysis and Pushover analysis are adopted to study steel brace and viscous damper brace systems with continuous layout and discontinuous layout. The analysis results indicate that the continuous brace layout has better performance of earthquake-resistance and toRsion-resistance, but it doesn′t meet the the requirement of architecture conception. The discontinuous steel brace system has the deficiency of irregular story shiffness that it is unfavourable for reducing the earthquake response and controling of torsion. The discontinuous viscous damper brace system makes up the shortage of the discontinuous steel brace system. It can assure the structure have enough performance of earthquake-resistance and torsion-resistance and can coordinate the architecture and structure layout to meet the requirement of architecture conception.

Keywords:high-rise structure; column and brace system; viscous damper; control of torsion
