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 elasto-plastic analysis method is introduced. Based on the three-level design objective and two-stage design method of seismic design in our country, the application of SAP2000 and YJK software to calculate the stress of a reinforced concrete frame structure under frequent earthquakes was carried out. The structure of the structure was subjected to static elasto-plasticity Analyzes and calculates its layer displacement angle under rare earthquakes and compares it with the failure state of the structure. The calculation results show that the frame structure meets the design requirements of China earthquake resistance norms small earthquake is not bad, big earthquake does not fall.
