- 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.
