摘要
在分析FRP约束混凝土矩形截面柱受力机理的基础上,建立了FRP约束混凝土矩形柱截面的有效受压区的计算模型,结合已有的试验数据,提出了FRP加固混凝土轴心受压矩形截面柱极限承载力的实用计算公式.
Based on analyzing the mechanical behavior of the concrete rectangular column,a model of the effective confined zone is proposed.Through the exsiting test results,a practical expression of the ultimate bearing capacity of the column strengthened with FRP is proposed.
