高耸结构地震动力分析
Seismic Dynamic Analysis on Tall Buildings
【摘要】 在对2000年姚安6.5级地震Ⅶ度区文峰塔和2004年保山5.0级地震Ⅵ度区文笔雁塔震害及结构进行调查分析的基础上,对这两个塔的结构进行了简化,计算了两个塔各层的地震加速度,并对其进行对比分析。结果表明,当加速度值≥0.08g时,塔的某些部位开始破坏。
【Abstract】 Wenfeng Tower is located in the intensity Ⅶ area of the 2000 Yao’an,Yunnan,MS6.5 earthquake,and Wenbiyan Tower in the intensity Ⅵ area of the 2004 Baoshan,Yunnan,MS5.0 earthquake.On the basis of the data of seismic disasters and structures of the two towers,we simplified the towers’ structures,calculated the acceleration of erery floor of the towers,and gave their comparative analysis.The results show that the power will begin to destory in some parts when the acceleration is higher than or equal to 0.08 g.
