大底盘多塔高层结构抗震设计

Seismic design of an multi-tower high-rise structure with base block

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。

The multi-tower high-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 general high-rise buildings.How to do the seismic design and computational analysis of multitower structures in accordance with the specifications is a focus-solving problem of the structure design.
