[摘要] 中国农业银行苏州分行大楼存在标准层平面为“L”形，扭转不规则；局部楼板不连续；局部竖向构件不连续等，属于特别复杂的高层建筑结构，给结构设计带来了一定的困难。结合抗震规范的要求，采用基于性能的抗震设计方法，对主体结构进行了详细的弹性和弹塑性抗震分析。分析结果表明，在地震作用下，主体结构具备较好的承载和变形能力，通过罕遇地震作用下的弹塑性分析计算，找出了结构潜在的抗震薄弱部位和薄弱构件，并提出相应的抗震加强措施，为工程设计提供了参考。

Abstract: Suzhou ABC tower is a complex engineer, and plan like “L”, anti-regularity of torsion, the bigger ration of hole on the floor and local transfer of vertical components are existed in the structure. Combined with the requirements of the national anti-seismic norm, the performance-based seismic design is used, and the elastic and elastic-plastic analyses are carried out. The analysis results indicate that under the earthquake, the main structure has good bearing and deformation ability. By the analysis of elastic-plastic under large earthquake, the weak parts in seismic performance are found, and the seismic strengthening measures are suggested.
Keywords: ultra limit complicated structure; performance-based seismic design; pushover analysis
