Seismic Vulnerability Factors Analysis of Masonry Structure Based on IDA
摘要
对于建筑物或其他结构在地震发生时发生破坏的概率或可能性
并没有准确的数理函数表示。基于增量动力弹塑性时程分析方法(IDA)
针对地震发生时更易发生破坏的砌体结构
从场地条件、横墙面积比、高宽比3个因素入手。选取数个典型结构
对震害发生时
针对不同类型的砌体结构抗震能力进行易损性分析
并给出合理建议。
Abstract
For earthquake damage to buildings or other structures
there is no accurate mathematical functions to express.This article is based on the incre mental dynamic analysis.Because the masonry structure is likely to be collapsed at the time of earthquake
based on the site conditions
the cross wall area ratio and the height-width ratio these three factors.We select several typical structures
according to different types of masonry structure to make vulnerability analysis.In the end we put forward some reasonable suggestions.
