摘要: 某连体建筑两侧塔楼体型差异较大,为超限高层复杂连体建筑,采用框架-剪力墙+连体桁架的结构体系.针对连体桁架结构选型进行优化分析,针对连体结构整体模型,进行小震弹性分析、中震性能化验算和大震动力弹塑性分析. 随后对连体结构的关键问题进行了研究,包括关键构件和节点的设计、抗连续倒塌能力以及大震下结构的变形和损伤情况. 分析结果表明,超限高层复杂连体结构的结构体系合理,具有较好的整体性,关键构件和节点的设计均能达到预设的性能目标,且连体结构具有较好的抗连续倒塌能力.

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
