CFRP布条带约束混凝土圆柱承载力计算方法研究

Study on the calculation method of circle concrete column wrapped with CFRP cloth straps

通过6根CFRP布条带约束混凝土圆柱静载试验,研究CFRP布条带约束对混凝土柱承载力和变形的影响规律。试验结果表明:随着条带包裹层数的增加,CFRP布条带约束混凝土柱承载力和变形均有一定幅度的提高。依据试验及理论分析,提出适用于CFRP布条带约束混凝土柱的承载力计算方法,可为工程设计人员提供一定的参考。

By the axial compression tests on a total of 6 concrete columns wrapped with CFRP cloth straps, the influence of CFRP cloth straps on the axial compressive strength and deformation was studied.The test results indicate the bearing capacity and ductility of concrete columns were increased with the increase of the layer of CFRP cloth straps.The simplified calculation method of bearing capacity was sum- marized based on test data and theoretical analysis, which can provide a reference for engineering designer.
