      Experimental study on seismic behaviors of concrete columns reinforced with SRF

      摘要:
      为了研究高延性聚酯纤维材料的加固效果,对5根钢筋混凝土柱(其中4根用高延性聚酯纤维带加固)在低周反复荷载作用下进行试验,比较分析了用高延性聚酯纤维材料加固(SRF)前后混凝土柱的破坏形态、滞回曲线、极限承载力和延性系数等,结果表明:SRF加固能够使柱的抗震性能得到改善,增加高延性聚酯纤维带的层数和塑性铰区加固钢筋的长度,使得SRF加固效果更好.
      Abstract:
      In order to study the reinforcement effect of high ductile polyester fiber materials,this study tested five reinforced concrete columns including four columns strengthened with high ductility polyester fiber subjected to lateral cyclic loading.The failure mode,hysteretic behavior,ultimate capacity and ductility factor were analyzed.Test results revealed that SRF reinforced concrete columns can improve the seismic performance of the columns.Meanwhile,increasingthe number of layers of the high ductile polyester fiber and the length of the reinforced hinge reinforcement bars can improve the SRF reinforcement effects.
