摘要
通过8组混凝土试件的轴心受压试验,研究分析碳纤维布条带宽度和间距等不同试验参数对约束效果的影响。试验结果表明,各种形式碳纤维包裹的混凝土棱柱体的承载力都有一定程度的提高,延性增大,破坏过程与没包裹碳纤维布的试件相比缓慢。
The effect of different test parameters such as width and spacing of straps of CFRP sheets on confining concrete column is studied and analyzed, through eight groups of concrete test columns subjected to axial loading. The test results show that the axial compressive strength and ductility of concrete prism wrapped by CFRP sheets or CFRP straps have all increased to a certain degree,the process of destruction of concrete prism wrapped by CFRP become slower than common concrete prism.
