［摘要］同濟大學(xué)教學(xué)科研綜合樓屬平面和豎向都不規(guī)則的復(fù)雜高層結(jié)構(gòu)體系。建筑旋轉(zhuǎn)上升的功能平面布局以及設(shè)備夾層的設(shè)置給結(jié)構(gòu)體系選擇和結(jié)構(gòu)設(shè)計帶來了相當大的難度，尤其是樓層功能平面的螺旋上升布置，將導(dǎo)致結(jié)構(gòu)在地震作用下呈現(xiàn)明顯的扭轉(zhuǎn)不規(guī)則特征。詳細介紹了同濟大學(xué)教學(xué)科研綜合樓結(jié)構(gòu)分析與設(shè)計，包括結(jié)構(gòu)體系選型、粘滯阻尼支撐的創(chuàng)新應(yīng)用、包括Pushover分析在內(nèi)的全面抗震分析、結(jié)構(gòu)模型振動臺試驗結(jié)果以及關(guān)鍵節(jié)點的設(shè)計。結(jié)構(gòu)分析和模型試驗結(jié)果均表明，合理的結(jié)構(gòu)選型和結(jié)構(gòu)設(shè)計有效地解決了結(jié)構(gòu)規(guī)則性超限的問題，使地震作用下的結(jié)構(gòu)反應(yīng)實現(xiàn)了規(guī)則化。

Abstract:Teaching and Research Complex of Tongji university is a complex high-rise steel structure with characteristic of plane irregularity and vertical irregularity. Its unique spiral layout of L-shaped block units and six facility floor brought very great challenges to the structural system selection and structural design, in which the most critical is to reduce the torsion effect from the spiraling layout of building block units when earthquake occurs. The structural analysis and design are presented, including structural system selection, creative application of viscous damper brace, comprehensive aseismic analysis (including Pushover analysis), shaking table test and critical joint connection design. Structural analysis and shaking table test show that through t

he rational structural system selection and design, the problem of the structural regularity beyond the code limit is solved effectively and regular structural effect is achieved.

Keywords:high-rise steel structure; viscous damper brace; aseismic analysis; shaking table test
