对某具体项目进行了罕遇地震下的弹塑性时程分析计算，依据得出的结果，对结构在罕遇地震下的抗震性能进行了评估，论证了结构实现“大震不倒”抗震设防性能目标的方法，以供参考。%The paper undertakes the elastic-plastic time-procedure analysis of some program under rare earthquakes, concludes the anti-seismic e-valuation under the rare earthquakes, and proves the methods to realize the seismic fortification performance aims of“earthquake does not fall”, so as to provide some reference for other projects.
