摘要
本文进行了 4根钢筋混凝土短柱 (λ =1 5 )在周期性反复荷载作用下的试验 ,研究了使用碳纤维布横向包裹钢筋混凝土短柱以提高其延性这种加固方法的有效性。本文研究了碳纤维布横向包裹钢筋混凝土短柱的受力特性 ,分析了碳纤维布抗拉强度对试件抗震性能的影响 ,并对碳纤维布加固钢筋混凝土短柱使其延性提高的机理进行了探讨。试验结果表明 ,横向包裹碳纤维布可显著提高钢筋混凝土短柱的变形性能。
Four reinforced concrete short columns ( λ =1 5) under cyclic loading were t ested.The effectiveness of the new method of using continuous carbon fiber sheet (CFS) on strengthening reinforced concrete short columns for increasing their s eismic behavior is studied.Tensile strength of CFS affecting the seismic behavio r of the specimens was analyzed.The confinement mechanism of CFS to reinforced c oncrete short columns was also proposed.The experimental results indicate that t he seismic behavior of the reinforced concrete short columns ( λ =1 5) is im proved remarkably. \
