根据纤维增强复合材料(Fiber Reinforced Plastics)侧贴加固钢筋混凝土构件受弯性能的试验研究，对受弯破坏形态和设计要求进行了讨论。基于平截面假定的正截面受弯承载力的计算理论，提出了FRP侧贴加固构件的正截面受弯承载力的实用计算方法。计算值与试验值吻合较好，并具有较高的可靠性，可供设计参考。探讨了《混凝土结构加固设计规范》(GB 50367-2006）中由梁底改贴到梁两侧面的FRP截面积修正系数ηf的取值情况:在hf/h为定值时，ηf并不象《混凝土结构加固设计规范》所示为定值，而是随加固梁各参数的变化而变化。

The bending failure modes of and design requirements for Reinforced Concrete(RC) member strengthened with side-bonded Fiber Reinforced Polymer(FRP) are investigated through tests on its flexural behavior. With theoretical method of calculating flexural capacity on the positive section based on the assumption of plane section, a practical calculation method for the flexural strength reinforced with side-bonded FRP is put forward. The calculated values, which are well consistent with the test data, are reliable and  can be referential for  designers. The study also probed into the values of correction coefficient ηf in Design Code for Strengthening Concrete Structure (GB 503672006) when FRP is bonded on the sides of RC beams rather than on the bottom. When hf/h is a fixed value, the correction coefficient ηf is not a definite value as shown in the design above code, but varies with the parameters of the strengthened RC beams.
