| 摘 要： | 对5个不同损伤程度的框架节点采用玄武岩纤维加固后进行低周反复荷载试验。考虑混凝土框架节点受损修复后初始损伤的影响,提出构件修复后混凝土承载力折减系数;基于现行设计规范,建立玄武岩纤维加固混凝土框架节点考虑构件初始损伤的承载力计算公式,为震损混凝土构件的加固设计提供参考。

| Abstract: | Low-cycle reverse loading tests are conducted on five varying degrees damage frame joints strengthened by BFRP.Considering initial damage on strengthening effect of repaired frame joints,bearing capacity reduction factor of repaired concrete is proposed.Bearing capacity design formulas considering initial damage of RC frame joints strengthened with BFRP are given,thereby providing references for evaluation of bearing capacity and reinforcing design of earthquake damaged members. |
