摘　　要：本文阐述了基于Push-over分析的抗震评估方法,提出使用层间位移角以及结构在大震下的塑性铰转角来评估框架结构的抗震性能,给出了新的抗震性能评估的步骤。使用本文所推荐的方法对一实际工程进行了抗震性能评估,并且与现行建筑抗震鉴定标准所推荐的方法对比,结论一致。结果表明,该方法从结构整体性能分析出发,可以快速有效地评估结构的抗震性能,该方法也可以为结构加固后的抗震性能评估奠定基础。Based on Push-over analysis, a new method of seismic evaluation for reinforced concrete frame structure is introduced. Story drift and plastic hinge comer are used to evaluate reinforced concrete structure. From the applied illustration, it can clearly be seen that this method can quickly and scientifically evaluate reinforced concrete frame structure as structure is overall analyzed. At the same time, conclusions are similar to experience method advised by Code of Seismic Appraiser of Buildings.
