【摘要】 通过 3根钢筋混凝土柱在周期反复荷载作用下受力性能的试验研究 ,验证了用碳纤维布包裹钢筋混凝土柱来提高其延性这种补强加固方法的有效性 ,分析了碳纤维布的包裹范围、包裹方式等因素对补强加固效果的影响 ;同时编制了计算机全过程受力分析程序 ,分析了较高轴压比情况下构件延性的变化情况 ,为进一步研究奠定了基础。更多还原

【Abstract】 Based on the experiment of three reinforced concrete columns under cyclic loading,the effectiveness of the new method of using carbon fibre sheet(CFS) on strengthening the reinforced concrete columns for increasing their ductilities is examined and the factors such as wrapping area and wrapping manners are analyzed.At the same time,a computer program is developed to analyze the ductility of the columns under higher axial compression ratio.更多还原
