双线性隔震器最佳屈服平台研究
|
摘要
隔震器的屈服平台是和地震输入到隔震结构的能量吸收与反应有关的重要参数之一.本文主要研究了决定隔震器的屈服力(Qy)与结构的总重(W)的最佳比值.基于基础隔震结构的能量设计方法,推导出适用于双线性隔震器最佳屈服平台的应用公式.根据选取不同的隔震层参数,与国外学者采用的实验方法予以分析比较,得出几点相关规律.
The yield level of isolator is one of the important parameters relevant to the absorption and reaction of the energy reaching the seismic isolated structure.In this paper,the main purpose is to determine the best ratio between the isolator yield force(Qy) and the overall weight(W) of the structure.Based on the energy design measures for base-isolation structure,the formula applicable to the optimal yield level of the bilinear isolator is derived.Comparing the selected parameters of different isolation layers with foreign scholars' experimental methods,a few related rules are derived.
