[论文][Paper]不同抗震等级RC梁抗震性能试验研究

通过9根钢筋混凝土梁的低周往复试验,对比研究不同抗震等级RC梁的破坏形态、延性、滞回性能、耗能能力及刚度退化等。结果表明:剪跨比为2.0的试件发生弯曲滑移破坏,剪跨比为3.0的试件和剪跨比为4.2的试件发生弯曲破坏;剪跨比为2.0的试件抗震等级分别为二级和四级,表明满足规范抗震等级要求的RC梁试件无法避免发生弯曲滑移破坏;同组试件中,抗震等级越高(配箍率越大),试件的极限位移角越大。除去发生弯曲滑移破坏的试件,试件的极限位移角随抗震等级的提高呈线性增长趋势;抗震等级相同时,弯曲滑移破坏的试件刚度退化比弯曲和弯剪破坏试件严重;弯曲滑移破坏与弯曲破坏的RC梁试件其耗能分别集中在塑性阶段的前期和中后期。
