摘要: 某連體建筑兩側(cè)塔樓體型差異較大,為超限高層復(fù)雜連體建筑,采用框架-剪力墻+連體桁架的結(jié)構(gòu)體系.針對(duì)連體桁架結(jié)構(gòu)選型進(jìn)行優(yōu)化分析,針對(duì)連體結(jié)構(gòu)整體模型,進(jìn)行小震彈性分析、中震性能化驗(yàn)算和大震動(dòng)力彈塑性分析. 隨后對(duì)連體結(jié)構(gòu)的關(guān)鍵問題進(jìn)行了研究,包括關(guān)鍵構(gòu)件和節(jié)點(diǎn)的設(shè)計(jì)、抗連續(xù)倒塌能力以及大震下結(jié)構(gòu)的變形和損傷情況. 分析結(jié)果表明,超限高層復(fù)雜連體結(jié)構(gòu)的結(jié)構(gòu)體系合理,具有較好的整體性,關(guān)鍵構(gòu)件和節(jié)點(diǎn)的設(shè)計(jì)均能達(dá)到預(yù)設(shè)的性能目標(biāo),且連體結(jié)構(gòu)具有較好的抗連續(xù)倒塌能力.

Abstract: The shape of towers on both sides of a connective building is quite different, it belongs to an out-of-code tallbuilding with complex connective structure. The frame-shear wall structural system with connecting truss was adopted. Thetruss type selection of connective structure were analyzed and optimized. The elastic analysis of frequently-occurredearthquake, performance based seismic design of fortification earthquakes and the dynamic elastic-plastic analysis of rarelyoccurred earthquake were carried out. Finally, the key points of connective structure were discussed, including design ofkey members and joints, the capability of the anti-progressive collapse,the deformation and damage of the structure underrarely-occurred earthquake. The analysis results show that the adopted structure system is suitable to the out-of-code tallbuilding with complex connective structure and has well integrity, the design of key members and joints can reach theprescribed performance target and the connective structure has well anti-progressive collapse capability.

Keywords:out-of-code high-rise building; complex connective structure; connecting truss; anti-progressive collapse
