摘要
在基础隔震系统实用简化模型基础上,建立了相应的结构地震反应时程分析方法,并进行了地震波下上部结构加速度反应谱及基础位移反应谱计算.对隔震结构地震反应的特性及隔震参数的选取作了分析研究.本文所提供的计算方法是解析方法,精确可靠,适用性强,对建立隔震结构实用设计方法,推广该体系的应用范围具有一定意义.
In this paper, the time analytical method of the earthquake response for the isolating structure is established on the base of the simple mode suggested by authors , and compute the response spectra of the supper structure acceleration and the base displacement. Therefor, authors reseach into the earthquake response characteristic and the choice for isolating bearings. The method is analytical, accurate, reliability, useful and meaningful for establishing the useful design method of the isolating structure and popularizing application.
