摘　　要：为研究不规则混凝土框架结构的抗震性能,结合中卫南站房实际情况,提出其抗震性能目标和钢拱架的抗震设计指标,基于性能的抗震设计方法,对结构进行多遇地震弹性、罕遇地震静力弹塑性(Pushover分析)和动力弹塑性时程分析。研究结果表明:站房整体结构抗震性能良好,钢拱架作为关键构件,其抗震性能目标满足并超出预设的性能水准;对于典型平面布置的铁路中小型站房,罕遇地震作用下,可考虑对其仅进行静力弹塑性分析。The study focuses on the seismic performance of irregular concrete frame structures.According to the actual situation of Zhongwei south railway station,the performance objectives and design specifications of its key components are put forward.Based on the performance-based design method,the performances of its structure are verified through the elastic analysis of frequent earthquake,elastic-plastic static analysis and elastic-plastic dynamic analysis of rare earthquake.The results show that the overall seismic performance of its whole structure is good and that the three continuous steel arches as the key component meet and exceed the preset seismic performance objectives.For small and medium-sized railway stations,the elastic-plastic static analysis of rare earthquake is recommended.
