Abstract

In this paper, a closed-form rigorous solution for interfacial shear stress in simply supported beams strengthened with bonded prestressed E-FGM plates and subjected to an arbitrarily positioned single point load, or two symmetric point loads is developed using linear elastic theory. This improved solution is intended for application to beams made of all kinds of materials bonded with a thin plate, while all existing solutions have been developed focusing on the strengthening of reinforced concrete beams, which allowed the omission of certain terms. The theoretical predictions are compared with other existing solutions. Finally, numerical results from the present analysis are presented to study the effects of various parameters of the beams on the distributions of the interfacial shear stresses. The results of this study indicated that the E-FGM plate strengthening systems are effective in enhancing flexural behavior of the strengthened RC beams.

预应力指数变性能板加固RC梁界面剪应力的分析

本文利用线弹性理论，推导了任意位置的单点或两个对称点荷载作用下有粘结预应力E-FGM板加固简支梁界面剪应力的闭合形式严格解。这种改进的解决方案旨在应用于由各种材料制成的与薄板结合的梁，而所有现有的解决方案都专注于钢筋混凝土梁的加固，这允许省略某些术语。将理论预测与其他现有解决方案进行了比较。最后，给出了本分析的数值结果，以研究梁的各种参数对界面剪切应力分布的影响。研究结果表明，E-FGM板加固体系能有效地提高加固后钢筋混凝土梁的受弯性能。
