In this paper,the permissible tensional prestress of the RC beams strengthened with prestressed CFRP is discussed in terms of the tensile strength of concrete,the shear strength of interface between concrete and CFRP,and the tensile strength of CFRP.
文中从混凝土抗拉强度、混凝土和CFRP层界面抗剪强度以及CFRP抗拉强度控制3个方面出发,探讨了预应力CFRP增强RC梁的容许张拉预应力值,并通过算例分别计算了混凝土拉裂缝产生、界面剥离以及CFRP先于钢筋破坏时的容许张拉预应力值,发现界面发生剥离时的容许张拉预应力值最低。
