| 摘 要： | 以某二层钢筋混凝土工业厂房的一榀框架结构为原型,按1:3的缩尺模型,设计了钢筋混凝土框架试件,并对该框架的粱端、柱端及节点进行碳纤维布加固,然后对该框架进行水平低周反复荷载的试验.基于试验结果.主要分析了碳纤维布加固完好钢筋混凝土框架试件的裂缝发展、抗震能力及破坏特点,绘出了试件的滞回曲线、骨架曲线和柱端钢筋及CFRP布的滞回曲线.研究了碳纤维布加固完好混凝土框架结构的抗震性能.试验结果表明,碳纤维布加固完好混凝土框架结构具有良好的抗震性能和滞回耗能能力.

| Abstract: | Based on two layers of industry workshops as project background,a R.C frame test model was designed with the scale 1:3.The end of beam and column and nodes of the framework were reinforced by CFRP.The experiments under low-cycle and repeated load are carried out.Based on the test under low-cycle and repeated loads,the curves such as load-displacement hysteresis curve,load-skeleton curve,hysteresis curves of the steel bar and CFRP of column end are drawn out and seismic properties of the perfect R.C frame st... |
