[摘要] 大底盘多塔楼高层建筑的结构振型复杂，并会产生复杂的扭转振动。其振动特性、受力性能、破坏形式、分析模型及计算方法要比一般高层建筑复杂得多。如何按照规范进行多塔楼结构的抗震设计与计算分析，成为结构设计中应当着重解决的问题。

Abstract: The multi-tower lugh-rise building with base block has complex vibration modes, and produces the complex torsion vibration. Its vibration characteristics, mechanical behavior, failure mode, analysis model and calculation method are much more complex than generallugh-rise buildings. How to do the seisnuc design and computational analysis of multi- tower structures in accordance with the specifications is a focus-solving problem of the structure design.
Keywords: multi-tower structure with base block; seismic design; irregularly plan
