高层隔震建筑风振响应研究

摘要
本文对比分析了高层隔震建筑和高层非隔震建筑的风振响应,并重点分析了高层隔震风振响应特点。首先,根据铅芯橡胶隔震支座和上部结构的力学特点,分别建立了高层隔震和高层非隔震的空间有限元模型;其次,基于引入时间抽取快速离散傅立叶变换的谐波叠加法,使用Matlab编程语言模拟出高层建筑空间相关脉动风速,把所模拟出的风荷载施加到隔震与非隔震三维空间有限元模型的相应节点上,对比分析隔震和非隔震建筑风荷载响应特点,并建议了高层隔震建筑抵抗风荷载应采取的措施。
In this paper,the wind-induced respond of tall-story isolation and tall-story non-isolation are analyzed and compared,and the wind-induced respond characteristic of tall-story isolated building is mainly studied.First,space finite element models of tall-story isolation and tall-story non-isolation have separately been established.Secondly,based on the method of DIT-FFT WAWS,the respond speed of pulse is simulated by the program of Matlab,and the wind load which is simulated is put on the correspond joints of space finite element models of isolated structure and non-isolated structure.The wind-induced respond characteristic of tall-story isolated building,and advice how to do with the problem which tall-story isolation resisted wind load are presented.
