摘　　要：针对某顶部设置连体的双塔大跨连体结构,采用通用有限元程序建立了精细的计算模型,分别进行了振型分解反应谱分析、弹性动力时程分析及弹塑性静力推覆分析,揭示了此类结构在地震作用下的受力性能和反应特点,用能力谱法对结构的抗震能力进行了初步评价,数值结果为工程设计提供了一定的参考依据。The fine FEM computational model for a multi-tower building with top connecting floors was established by using a general purposed finite element program. Earthquake responses and seismic performance of the building structure were studied by meanings of response spectrum analysis, elastic time history analysis as well as push-over analysis. Response deformation and reaction mechanism of the structure to earthquake loads were discussed in some details. Its seismic performance ability was preliminarily evaluated by the capacity spectrum method. Numerical results may also provide certain reference to the practical engineering.
