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。 There is no exact mathematical representation of the probability or likelihood of a building or other structure disrupting an earthquake. Based on the incremental dynamic elasto-plastic time-history analysis (IDA), aiming at the masonry structure that is more prone to damage in the event of an earthquake, three factors of site conditions, aspect ratio and aspect ratio are taken into account. A few typical structures were selected to analyze the vulnerability of different types of masonry structures to earthquake damage and give reasonable suggestions.
