| 摘 要： | 地震易损性分析对空间结构等重要结构的风险评估以及基于性态的抗震设计具有重要意义。讨论了不考虑下部支撑结构的单层球面网壳结构的理论易损性曲线建立方法及其基本步骤,并进行了算例分析。将各种结构参数进行Monte-Carlo模拟,并随机选取80条地震记录组成了80个结构样本对,用Abaqus软件对每个样本进行了考虑材料损伤累积的增量动力分析,得到了其地震易损性曲线。

| Abstract: | Seismic vulnerability analysis is of great importance to risk assessment and performance-based seismic design of structure.A method and its basic steps of seismic vulnerability analysis for single-layer reticulated dome without its substructure is provided and was performed to a reticulated dome model.Monte-Carlo simulation was performed to several structure parameters and 80 seismic records were chosen at random.To each sample,increment dynamic analysis(IDA) is performed with the software Abaqus considering material accumulation.In this way,seismic vulnerability curves of the model are obtained. |
