摘要:
基于反应谱理论的隔震结构简化计算需要寻求并建立适合长周期和大阻尼比情况下的反应谱。文中指出规范反应谱及其拟相对位移反应谱在长周期部分存在的问题,对规范反应谱是否可用于隔震结构简化计算进行了分析,然后通过建立隔震结构反应谱,比较了隔震结构反应谱拟谱与真谱差异,分析了造成这些差异的原因,最后以算例具体分析规范反应谱理论的"由地震作用求地震作用效应"方法在隔震结构中的适用性。
Abstract:
Simplified calculation of a isolated structure based on theory of response spectra needs to seek and establish response spectra that are suitable for a structure with long natural period and large damping ratio.Some issues existed in long period part of code response spectrum and pesudo response spectrum a pointed out in this paper,and whether code response spectra are suitable for simplified calculation of the isolated structure are also analyzed.Based on the analyses,differences between pseudo and real response spectra of the isolated structure are compared and analyzed,further more the reasons caused these differences are discussed.In the end,the suitablity of the method widely used in theory of code response spectra,that is the seismic action effect is solved from earthquake action,is analyzed concretely with one project example.
