框架柱铰的动力反应及耗能分析
|
摘要
针对普通方箍柱、井字式复合配箍柱和内埋工字钢柱绞在低周反复荷载作用下的实测滞回特性，提出了相应的动力分析恢复力模型，并编制了地震作用下的弹塑性动力分析程序，采用ＥＬＣｅｎｔｒｏ波和两种人工波，对３种框架柱铰进行了不同地震量级作用下的动力反应和耗能过程计算分析，结果表明，井字式复合配箍柱和内埋工字钢柱具有良好的抗震性能．
According to tested hysterestic characteristics of columns hinge with ordinary,with #shaped composite stirrups and with I shaped steel under cyclic loading, dynamic analysis recoveringforce models is presented. The elasto-plastic dynamic analysis program was compiled under earthquakeon the basis of analyzed results. Dynamic response and energy disspation process of tested column indifferent earthquake input are calculated.Calculations show that column with # shaped compositestirrups and with I shapod steel had better earthquake-resistant behaviour and can endure strongearthquake.
