碳纤维板加固混凝土梁的锚固剪应力参数分析

Parameter Analysis of Bonding Shear Stress of RC Beams Strengthened with CFRP Plates

在CFRP加固混凝土梁的锚固剪应力计算公式基础上,对集中荷载作用下的锚固剪应力进行参数分析,结果表明,锚固剪应力主要和CFRP板的厚度、弹性模量以及黏胶层的厚度与弹性模量有关。计算结果可供桥梁结构的加固设计参考。

Based on the formula for calculating the bonding shear stress of a RC beam strengthened by CFRP plate,the parameter analysis of the bonding shear stress with the concentrated forces is presented in this paper.The results show that the bonding shear stress is influenced not only by the thickness,the elastic modulus of the CFRP plate,but also by the thickness and the elastic modulus of the adhesive.The conclusions can be referred to the strengthening design of the bridge structures.
