摘　　要：通过8根碳纤维布约束混凝土方柱的轴心受压试验,研究分析了碳纤维布条带间距和包裹层数等参数对约束效果的影响.结果表明,各种形式碳纤维布包裹的混凝土方柱的承载力都有一定程度的提高,延性增大.整体包裹效果明显优于条带包裹.所选取的碳纤维增强复合材料约束混凝土方柱的抗压强度模型的计算结果与试验实测值吻合较好.The experimental results show that the axial compressive strength and ductility of concrete square-columns wrapped by CFRP sheets or CFRP straps have increased to a certain degree,and the confining effect of whole wrap was better than straps wrap.The calculated results on the basis of models selected for predicting compressive strength are in good agreement with test data.
