[摘要] 大底盤(pán)多塔樓高層建筑的結(jié)構(gòu)振型復(fù)雜，并會(huì)產(chǎn)生復(fù)雜的扭轉(zhuǎn)振動(dòng)。其振動(dòng)特性、受力性能、破壞形式、分析模型及計(jì)算方法要比一般高層建筑復(fù)雜得多。如何按照規(guī)范進(jìn)行多塔樓結(jié)構(gòu)的抗震設(shè)計(jì)與計(jì)算分析，成為結(jié)構(gòu)設(shè)計(jì)中應(yīng)當(dāng)著重解決的問(wèn)題。

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
