| 摘 要： | 鉴于用力学平衡方法推导纤维增强塑料(FRP)加固混凝土圆形短柱轴心受压强度公式时，不少实验中柱破坏时FRP未达极限应变，引入了FRP强度发挥系数k，对加固后强度理论值作出了修正，给出了FRP加固混凝土圆形短柱的抗压强度公式，并将文中理论值与Demers试验实测值进行了对比。

| Abstract: | Based on mechanical equilibrium, a formula for calculating the compressive strengths of concrete short columns wrapped with fiber reinforced plastics (FRP) is deduced. The strains of FRP do not reach their limit while strengthened columns are damaged in many experimens. On account of the fact mentioned above, this study introduced an efficiency coefficient of fiber reinforced plastics, which revise the compressive strengths of strengthened columns, thus proposing a method for determining the compressive strengths of circular short columns wrapped with FRP. The theoretical results in this paper are compared with the test results obtained by Demers. |
