| 摘 要： | 对受集中荷载作用的预应力FRP片材增强钢筋混凝土梁的界面应力分布进行了理论分析.在弹性理论的基础上,对结构进行受力分析,推导出集中荷载作用下界面剪应力和正应力的计算公式.结果表明,界面正应力不但与荷载和初始预应力的大小、梁的尺寸、粘贴层的弹性模量、剪切模量及厚度有关,还受到FRP弹性模量、厚度及粘贴长度的影响.界面正应力和剪应力在FRP的端部绝对值最大,并且往跨中方向迅速减小.

| Abstract: | This paper presents the theoretical analyses on the interfacial stress of RC beams strengthened with pre-stressed FRP.Base on the elastic theory,the structural interfacial stresses are analyzed,and the analytical solutions of normal stress and shear stress are obtained.The results show that the stresses depends on not only the initial pre-stress,loading,size of the beam,the elastic module and shearing module of the adhesive,but also the length,thickness and elastic module of FRP.The most maximum absolute va... |
