【摘要】 基于Pushover分析的抗震评估方法,提出了使用层间位移角以及结构在大震下的塑性铰转角来评估钢筋混凝土框架结构的抗震性能,给出了新的抗震性能评估步骤。使用所推荐的方法对一钢筋混凝土框架厂房进行了抗震性能评估,并且与实际震害记录对比,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评估奠定基础。更多还原

【Abstract】 A new method of seismic evaluation for reinforced concrete frame structure based on Pushover analysis 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 earthquake damage records. Reinforced frame can be evaluated by this method.更多还原
