Experimental and Analytical Study on Reinforced Concrete Beams in Bending Strengthened with FRP
The performance of the interface between fiber reinforced polymer (FRP) composites and concrete is one of the key factors affecting the behavior of strengthened reinforced concrete (RC) structures. Existing laboratory research has shown that RC beams strengthened with FRP sheets usually fail because of either debonding of the impregnated fabric from the concrete substrate or fracture of the FRP...
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 کاملDebonding-Related Strain Limits for Externally Bonded FRP Sheets in Flexurally Strengthened Reinforced Concrete Beams
Debonding problems of externally bonded fiber reinforced polymer (FRP) sheets in flexurally FRP-strengthened reinforced concrete (RC) beams have been a concern and a research challenge since their application of this strengthening technique. Intermediate crack induced debonding is the most common failure mode which is that the debonding initiates at the critical flexural-shear or flexural crack...
متن کاملEffect of Adhesive Viscoelasticity on the Creep Behaviour of FRP Strengthened Concrete Beams
This paper focuses on the effect of the viscoelasticity of the adhesive layer on the flexural creep response of reinforced concrete beams strengthened with composite materials. A theoretical model is developed, which considers the strengthened beam as a layered structure that consists of the reinforced concrete beam, the adhesive layer, and the FRP strip, and accounts for the creep of each comp...
متن کاملTHEORETICAL AND NUMERICAL STUDY ON THE STRENGTHENED STEEL PLATE SHEAR WALLS BY FRP LAMINATES
In this paper, nonlinear behavior of strengthened steel plate shear walls (SPSWs) by FRP laminates theoretically and numerically has been investigated. In the first part, a new method, “the composite-plate frame Interaction (C-PFI) method”, has been introduced to predict the shear behavior of the composite steel plate shear wall systems (CSPSWs). In the second part, several models of one-story ...
