摘要
通过对钢筋混凝土圆柱模型缠绕碳纤维布的轴心受压试验研究 ,详细介绍了用碳纤维布加固后的圆柱破坏特征 ,其受力性能及破坏机理 ,碳纤维布约束混凝土与钢筋及钢管约束混凝土的差异。并提出了用碳纤维加固钢筋混凝土柱的轴心受压承载力计算方法。
A test of concrete circular columns wrapped with carbon fiber fabric under axial compression is presented.The performing characteristic and confinement mechanism of CFRP wrapped columns are demonstrated in details.A satisfying theoretical model is suggested to predict the ultimate strength of CFRP wrapped circular columns under axial compression.
