摘要:

按1:3比例缩尺模型设计了1榀混凝土框架模型,进行了拟静力试验,分析比较了混凝土框架结构及该框架破坏后经碳纤维布加固后的框架结构受力性能、裂缝发展、破坏形态、滞回曲线、骨架曲线及位移延性,研究碳纤维加固已严重损伤的混凝土框架结构的抗震性能.试验结果表明,碳纤维加固震后严重损伤框架结构后,其极限承载能力、耗能能力及延性等抗震性能有明显提高.

Abstract:

The concrete frame model was designed according to the 1:3 scale scale-down model, and the quasi-static test was carried out, and the force performance, crack development, failure form, hysteresis curve, skeleton curve and displacement ductility of the concrete frame structure and the frame structure reinforced by carbon fiber cloth after the failure were analyzed and compared, and the seismic performance of the concrete frame structure that had been severely damaged by carbon fiber reinforcement was studied. The test results show that after the carbon fiber is seriously damaged after the earthquake, its ultimate bearing capacity, energy dissipation capacity and ductility and other seismic properties are significantly improved.
