摘要:

为了探讨震后损伤混凝土结构加固方案的优化,对两榀严重损伤的钢筋混凝土框架用角钢和碳纤维布进行复合加固(JKJ-A、JKJ-B),并对其进行模拟地震作用下的水平低周反复荷载试验.试验结果表明,随着节点角铜肢长的增大,复合加固框架的耗能能力和承载力增强,复合加回损伤框架与仅用碳纤维布加固的损伤混凝土框架相比有更好的承载能力.随着节点加固角钢肢长的增加,加固框架的抗震能力提高.

Abstract:

In order to explore the optimization of the reinforcement scheme of post-earthquake damaged concrete structures, the composite reinforcement (JKJ-A, JKJ-B) of the two severely damaged reinforced concrete frames was carried out with angle steel and carbon fiber cloth, and the horizontal and low-cycle repeated load tests were carried out to simulate the seismic action. The test results show that with the increase of the length of the copper limb at the nodal angle, the energy dissipation capacity and bearing capacity of the composite reinforced frame are enhanced, and the composite plus back damage frame has a better bearing capacity than the damaged concrete frame reinforced with carbon fiber cloth only. With the increase of the length of the joint reinforcement angle steel limb, the seismic resistance of the reinforced frame is improved.
