摘要
高层建筑结构,因体量庞大、质量巨大,如果建造于非基岩上,则结构的输入地震动也将大大有别于自由场地震动,其上、下部结构动力相互作用将是一个不容忽视的影响因素。本文围绕层状场域内高层建筑的地震动输入问题,针对目前普遍采用的将地基、基础与上部结构整体建模进行地震响应分析的整体法,提出了其合理的输入地震动的选取方法,并结合现行规范,为某实际工程进行地震响应分析的输入地震动进行了选取。
For the tall building structure with colossal vol.and vastness mass built on non-bedrock,the interaction of upper and lower parts will be not allowed neglect,the structural input seism would be highly different from free field ground motion.Centered on this problem,this paper aims at integral method,which means the analysis of seismic response on soil-foundation-superstructure integral model,adopted at large for the moment,the method of choosing the input seism on this model was brought forward.Moreover,bas...
