［摘要］成都来福士广场T1塔楼建筑平面为L形，建筑立面大开洞和悬挑造成结构平面和竖向均不规则，结构采用带斜撑的密排柱外框+剪力墙结构。针对结构复杂部位，采取了多种针对性的抗震加强措施，提高了关键构件的抗震设计性能目标；通过对结构进行弹性时程分析、重要桁架二道防线验算、施工过程模拟影响分析、动力弹塑性时程分析等多种分析手段，保证了结构的安全性。［关键词］成都来福士广场; 复杂超限结构; 性能化设计; 动力弹塑性分析; 转换桁架中图分类号：TU973.3 文献标识码：A 文章编号：1002-848X(2015)13-0012-05
Structural design of T1 tower of Raffles City in ChengduYue Lijie1,2, Sun Jianchao1, Wang Yang1, Liu Junjin1, Chen Ying1(1 China Academy of Building Research, Beijing 100013, China; 2 Beijing Vanke Co., Ltd., Beijing 100125, China)Abstract:The T1 tower of Raffles City in Chengdu with L-shaped plane, which have planar and vertical irregularities due to large openings in facade and cantilevers, adopts structural system of bracing frame with dense columns and shear wall. A variety of corresponding seismic strengthening measures were taken for complex parts of the structure to improve performance-based seismic design objective of key components. The safety of the structure was ensured by several analyses methods such as elastic time-history analysis, checking for second seismic line of important trusses, construction process simulation analysis and dynamic elastic-plastic time-history analysis.Keywords:Raffles City in Chengdu; complex out-of-code structure; performance-based design; dynamic elastic-plastic analysis; transferring truss
