通过对 7根不同灌浆情况下梁的低周反复加载 ,分析了构件的破坏特征、承载力状况 ;运用能量法分析了构件的耗能特性 ,以此来评价各个构件的抗震性能 ;验证了本文提出的角钢强度折减系数 as的取值 .通过试验可知 ,复合灌浆料可以替代环氧树脂灌浆 ,并且灌浆与否及饱满情况直接影响加固效果
The failure characteristics and the bearing capacity of the members were analyzed through repeated low-cycle loading of the beam under seven different grouting conditions. The energy dissipation characteristics of the members were analyzed by the energy method to evaluate the seismic performance of the members. Put forward the angle steel strength reduction coefficient as the value of the test shows that the composite grouting material can replace epoxy grouting grouting and grouting or not and the full case of a direct impact on the reinforcement effect
