框架结构房屋地震灾害风险评估
|
摘要
如何预测地震作用下建筑物的损伤风险,一直是地震工程和生命线工程领域的一个关键而不易解决的问题。利用大型有限元分析软件对上海浦东某医院框架结构进行了多地震非线性动力时程分析;针对延性破坏指标和强度破坏指标,计算了不同地震烈度下建筑物震害的严重程度,及5种破坏状态的发生概率,给出了震害率曲线。通过曲线,预测了类似建筑的震害,为城市抗震防灾政策的制定提供了依据。
It is very important in lifeline engineering to predict the vulnerability of building structures subjected to earthquake loading.The seismic vulnerability of frame structure is usually expressed with the fragility curves.SAP2000,large-scale finite element software,was used to complement the nonlinear time-history analysis of a hospital in Pudong,Shanghai.Two seismic fragility curves were presented according to the intensity damage index and the deformation damage index.The developed fragility curves can be used for emergency management and estimate of the overall loss after a scenario earthquake.
