摘　　要：介绍了静力弹塑性分析方法。结合我国抗震设计的三水准设计目标及两阶段的设计方法,应用SAP2000及YJK软件对一钢筋混凝土框架结构在多遇地震下的受力情况进行了计算;应用SAP2000对结构进行了静力弹塑性分析,计算了其在罕遇地震作用下的层间位移角,并将其与结构的破坏状态进行了对比。计算结果表明该框架结构满足我国抗震规范小震不坏、大震不倒的设计要求。The static elastic-plastic analysis method is introduced. Combing the three seismic fortificationlevels and two stages design method of our country,the mechanical behavior of a RC frame structure is cal-culated under frequent earthquake with the SAP2000 and Y JK software; the story dritt ratios structure are calculated under rare occurrence earthquake with the elastic-plastic method in SAP2000,the calculated story drift ratios are compared with the damage status data. The calculated result show that the RC frame structure satisfy the requirement that no damage under frequent earthquake and no collapse un-der rare occurrence earthquake in the Code for seismic design of building from our country.
