摘　　要：针对某高层双塔连体结构"头重脚轻"的不规则高层建筑,采用性能化设计思想,通过弹性阶段承载力和弹塑性阶段变形验算来确保结构的抗震安全性,并基于计算结果对结构方案进行优化调整.结果表明:采用基于性能的抗震设计方法能有效保障复杂结构的抗震安全性,相关思路及设计经验可供相同类型结构的抗震设计参考.A twin-tower tall building with connective structure is an irregular building with top-heavy.The performance-based seismic design method is adopted to ensure the seismic safety of buildings by use of elastic and elastic-plastic analysis.The structural scheme is adjusted based on the analysis results.It is shown that the seismic safety of the structure is ensured by performance-based seismic design method.Moreover,it provides reference for other similar buildings.

关 键 词：抗震设计 双塔连体结构 弹塑性时程分析
