［摘要］同濟(jì)大學(xué)教學(xué)科研綜合樓在地震作用下結(jié)構(gòu)呈現(xiàn)明顯的扭轉(zhuǎn)不規(guī)則特性，需設(shè)置必要的柱間支撐體系來控制扭轉(zhuǎn)效應(yīng)。采用非線性時(shí)程分析和彈塑性靜力分析，對(duì)鋼支撐和粘滯阻尼支撐兩類支撐的連續(xù)與非連續(xù)布置共四種支撐方案進(jìn)行對(duì)比分析。結(jié)果表明，連續(xù)支撐布置比非連續(xù)支撐布置具有更優(yōu)的抗震性能和抗扭性能，尤其是連續(xù)阻尼支撐布置，但與建筑立意不協(xié)調(diào)。非連續(xù)鋼支撐布置時(shí)層剛度不規(guī)則，不利于減小地震反應(yīng)和控制結(jié)構(gòu)扭轉(zhuǎn)。非連續(xù)粘滯阻尼支撐布置克服了非連續(xù)鋼支撐布置存在的不足，保證結(jié)構(gòu)具有足夠的抗震、抗扭性能，且能使得結(jié)構(gòu)布置與建筑相協(xié)調(diào)。

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
