［摘要］成都市第二人民医院龙潭医院为功能复杂的医疗综合体建筑，主要针对中部的超限双塔结构进行抗震设计论述。为保证该双塔结构达到预定的性能目标，采用振型分解反应谱法、弹性时程分析法及弹塑性时程分析法研究了双塔与单塔结构在地震作用下性能的异同，为后续施工图设计提供依据。

Abstract: The Second People′s Hospital of Chengdu Longtan Hospital is a medical complex building. Over-limit seismic design of the twin towers in the middle of the medical complex building was focused on. To ensure the twin towers to achieve the desired performance goals, mode superposition, elastic time history and elasto-plastic time history methods were used to study the similarities and differences of twin towers and the single tower under earthquake action, and the basis for subsequent construction drawing design was provided.

Keywords: seismic design; mode superposition; elastic time history; elasto-plastic time history
