摘要:
采用纤维增强塑料 (FRP)板对钢筋混凝土构件进行加固是近年来混凝土结构病害防治研究领域的一个新兴方向。该文基于钢筋混凝土结构设计理论中的截面平衡方程和应力应变关系 ,为FRP板加固的钢筋混凝土梁的计算提供了行之有效的理论和方法。以双筋矩形截面梁的计算分析为重点 ,给出了适用于单筋、双筋矩形截面梁和T形截面梁的计算公式 ,较好地反映了梁抗弯加固时正截面受力情况 ,对类似结构的加固设计也提供了有益的参考
Abstract:
In recent years, to strengthen the def icient reinforced concrete ( RC) members w ith f iber-reinforced polymer ( FRP) has been a booming f ield in the study on the protection and t reatment of concrete structure defect s. Based on equilibrium equat ions and stress-strain relat ionships, an effect ive theory and computational method for the analysis of RC beams st rengthened w ith FRP plates are presented. T hrough detailed discussion on the doubly RC rectangular sect ion, a set of formulae applicable to both sing ly and doubly RC rectang ular sect ions as w ell as T-sections, are deduced. It quite w ell describes the mechanical behavior of beam cross sections af ter rehabilitat ion with FRP plates and also prov ides v aluable reference to the design of similar structures.
