摘　　要：以太仓某体育馆为背景,利用PKPM、Midas等软件,先对结构进行多遇地震下的弹性分析,指出应采用"切分模型"包络分析等措施保证结构"小震不坏"的设防目标;后根据弹性分析结果进行配筋设计,对实际配筋结构进行罕遇地震下的静力弹塑性分析(Pushover),发现大震下薄弱部位主要位于一层,部分构件出现少量塑性变形,但远未达到倒塌状态,满足规范大震不倒的抗震设防目标.A three-dimensional space model of a concrete frame gymnasium was established using PKPM and Midas.The structural elastic seismic analysis under frequent earthquake was carried out and it was pointed out that the divided models and envelopment analysis should be adopted.Then the structure was reinforced and the Push-over analysis under rare earthquake was made.It was found that weak part was mainly in the first sto-rey and plastic deformation occurred in some structural members but they were still far from collapsing, so that the seismic fortification criterion“no collapse under rare earthquake” was fulfilled.
