| 摘 要： | 为研究大跨空间结构强震作用下性能水准的确定和量化，以凯威特单层球面网壳为例，确定了结构分级性能水准，采用多地震动全过程分析的方法建立了结构基于多项特征响应的损伤模型，应用此损伤模型刻画了结构不同的损伤程度，并给出了分级性能水准的界限值及对应的结构宏微观响应，从而实现了大跨空间结构分级性能水准易损性分析．

| Abstract: | To study the defining and quantification of the performance level of large span space structure under seismic motion,based on the single-layer kiewitt reticulated dome,this paper defines the graded performance level.And then the structural damage model based on the multiple dynamic responses using the whole course analysis method was conducted.The different damage degree,the boundary value of graded performance level and the corresponding dynamic responses were quantified by this damage model.At last,the vulnerability analysis of the graded performance level of large span space structure was completed. |
