大多数伊朗住宅建筑都是钢筋混凝土框架结构，里面填充了砖石墙。本文对钢筋混凝土框架结构的结构缺陷进行了概率地震评估。根据伊朗现行抗震规范进行了3层、5层和8层钢筋混凝土框架结构的抗震设计，并基于OpenSEES中的增量动力分析（IDA）进行了三维分析模型分析。得到了20组地震动记录以最大层间位移比为单位的需求统计，并根据HAZUS-MH极限状态确定了能力，最后绘制了相应的易损性曲线。研究结果反映了层数、结构缺陷和砌体填充墙对该亚类结构地震易损性的影响。
A majority of Iranian residential buildings have RC frame structures which are in-filled with masonry walls. Structural deficiencies of in-filled RC frame structures are focused in this probabilistic seismic assessment. The seismic design of 3, 5 and 8 story RC frame structures are carried out according to the current Iranian seismic code and then 3 dimensional analytical models analyzed based on Incremental Dynamic Analysis (IDA) in OpenSEES. The demand statistics in terms of maximum inter-story drift ratio are obtained for 20 sets of ground motion records and the capacity is determined according to the HAZUS-MH limit states and finally the corresponding fragility curves are developed. The results represent the effect of the story numbers, structural deficiency and masonry infill walls in the seismic vulnerability of this subclass of structures.
