Remote Detection of Debonding in FRP-strengthened Concrete Structures Using Acoustic-Laser Technique
Abstract Fiber-reinforced polymer (FRP) strengthening and retro fi tting of concrete elements, such as beams, columns, slabs, and bridge decks, have become increasingly popular. Nonetheless, rapid and reliable nondestructive testing techniques (NDT) that are capable of remotely assessing in-situ integrity of retro fi tted systems are needed. Development of a robust NDT method that provides an a...
متن کاملModeling of FRP-Strengthened Infill Masonry Structures
This paper presents an analytical approach to describe the behavior and mode of failure of infill masonry structures strengthened with fiber-reinforced polymer (FRP) materials. The approach is used to simulate the response of strengthened infill masonry walls under the effect of out-of-plane uniformly distributed pressure simulating wind pressure. The approach includes a finite element analysis...
متن کاملNovel Predictive Model of the Debonding Strength for Masonry Members Retrofitted with FRP
Strengthening of masonry members using externally bonded (EB) fiber-reinforced polymer (FRP) composites has become a famous structural strengthening method over the past decade due to the popular advantages of FRP composites, including their high strength-to-weight ratio and excellent corrosion resistance. In this study, gene expression programming (GEP), as a novel tool, has been used to predi...
متن کاملNumerical Simulation of Debonding Failure of Reinforced Concrete Beams Strengthened with Externally Bonded Frp
As the life age of the existing structures are required to meet the changing demands on civil infrastructures. So strengthening and retrofitting are required. Recently many techniques to strengthen the reinforced concrete beams in flexural by using fiber reinforced polymer (FRP) had appeared. The most famous technique among them is strengthening the (RC) beams with externally bonded FRP sheet t...
متن کاملAnalytical Modeling on Debonding Failure of Frp-strengthened Rc Flexural Structures
Effective application of FRP to concrete structure is not possible until a fundamental understanding of the mechanics and failure mechanisms of the retrofit system is available. This paper is mainly focused on developing a methodology for predicting the debonding failure caused by intermediate flexural cracks in FRP-strengthened R/C beam. Firstly, based on the strain compatibility, an iterative...
