（1 天津大学建筑设计研究院，天津 300073；2 天津大学建筑工程学院，天津 300072）［摘要］天津君临大厦是集商业、展览及办公等于一体的超高层综合性大楼。该楼采用钢筋混凝土剪力墙结构，建筑高度239.2m，远超规范7度抗震设防区B级高度150m限值，为此需对结构采用抗震性能化设计方法。采用两种软件对结构进行反应谱分析并对比，采用SATWE软件进行弹性时程分析及中震不屈服分析，利用PKPM-EPDA程序对结构进行弹塑性时程分析。根据结构自身的特点以及分析结果对结构薄弱部位采取加强措施，保证了中震时结构薄弱部位及重要部位不屈服，大震时结构薄弱部位及重要部位满足弹塑性变形要求。［关键词］超限高层; 钢筋混凝土剪力墙结构; 性能化设计; 弹塑性分析; 加强措施中图分类号：TU318 文献标识码：A 文章编号：1002-848X(2015)01-0001-04Structural design of super high-rise building of Tianjin Junlin BuildingYu Jinghai1, Li Luchuan2, Ding Yongjun1, Zhang Xizhi1（1 Architectural Design and Research Institute of Tianjin University, Tianjin 300073, China; 2 School of Civil Engineering, Tianjin University, Tianjin 300072, China)Abstract: Tianjin Junlin Building is a super high-rise comprehensive building, which contains business, exhibition, office and so on.It adopts reinforced concrete shear wall structure with the building height of 239.2m, which is far more than the limit of the code that is B-level height of 150m in 7 degree seismic fortification zone. For this reason, structural performance-based seismic design method was conducted. Using two programs, response spectrum analysis of the structure and comparison were conducted, as well as elastic time-history history analysis and the yield analysis under intermediate earthquake using SATWE software. Elastic-plastic time-history analysis of the structure was conducted using PKPM-EPDA software. Based on the characteristics of the structure and analysis results, the structural weak positions were strengthened by some measures, which ensure structural weak parts and important parts not to yield under medium earthquake, and to meet the requirements of elastic-plastic deformation under rare earthquake.Keywords: high-rise building beyond the cold-specification; reinforced concrete shear wall structure; performance-based design; elastic-plastic analysis; strengthening measure作者简介：于敬海，博士，研究员，一级注册结构工程师，Email: yjh300072@163.com。参考文献［1］GB 50009—2012 建筑结构荷载规范［S］.北京：中国建筑工业出版社，2012.［2］GB 50011—2010 建筑抗震设计规范［S］.北京：中国建筑工业出版社，2010.［3］JGJ 3—2010 高层建筑混凝土结构设计规程［S］.北京：中国建筑工业出版社，2011.［4］中国建筑科学研究院PKPMCAD工程部.PUSH&EPDA多层及高层建筑结构弹塑性静力、动力分析软件用户手册［M］.北京，2010.［5］曹倩，汪洋，赵 宏.复杂高层结构体系二道防线的探讨［J］.建筑结构，2011,41（S1）:331-335.
