摘　　要：在试验的基础上,对采用BFRP约束钢筋混凝土方柱试验强度和理论强度模型公式得出的强度进行了比较并研究了尺寸效应对加固效果的影响,分析结果表明:通过合理选择理论强度模型公式,可较好地计算纤维布加固混凝土柱的轴心受压性能,不同尺寸的混凝土方柱存在较明显的尺寸效应。Based on experiments, the strengths and influence of size effection to reinforcement effect of square concrete columns confined by BFRP were studied by and the strengths analysised were compared with experimental ones. The results suggest that uniaxial eompressed properties of specimens were predicted well by choosing finite element analysis model reasonably, square concrete columns of different sizes exist apparent size effection.
