摘要
对粘贴预应力FRP板加固砼梁中FRP板预应力的施加方法进行了分析和比较 ,并通过适当的理论计算分析 ,指出了各种方法的特点 .针对FRP板侧向强度低的特点 ,设计了一种新型的FRP板夹具 ,以对FRP板施加预应力 .分析和计算表明该夹具及相应的预加应力方法可操作性很强 .
Two methods of reinforced concrete beams strengthened with prestressed fiber?reinforced plastic plates on the tension face is analyzed.According to some academic calculation and analysis,their characters are given.Due to the weak side strength of FRP plate,a new type of clamping apparatus for prestressing FRP plate is given,which can give some suggestion to the experimental study and field application of maintenance and strengthening.
