Fatigue and Overloading Behavior of Steel-Concrete Composite Flexural Members Strengthened with High Modulus CFRP Materials

Due to corrosion and the continuous demand to increase traffic loads, there is a need for an effective system which can be used to repair and/or strengthen steel bridges and structures. This paper describes an experimental program, recently completed, to investigate the fundamental behavior of steel-concrete composite scaled bridge beams strengthened with new high modulus carbon fiber reinforce...

Flexural Testing of High Strength Reinforced Concrete Beams Strengthened with CFRP Sheets

The objective of this study is to investigate the effectiveness of externally bonded CFRP sheets to increase the flexural strength of reinforced high strength concrete (HSC) beams. Four-point bending flexural tests to complete failure on six concrete beams, strengthened with different layouts of CFRP sheets were conducted. Three-dimensional nonlinear finite element (FE) models were adopted by A...

Numerical 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...

Effect 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...

The Influence of CFRP Anchorage on Achieving Sectional Flexural Capacity of Strengthened Concrete Beams

This research program is intended to verify the influence of using distributed external U-wrap CFRP anchorage to shift the failure mode from overall debonding to sectional flexural failure for concrete beams externally bonded with CFRP sheets. Premature cover delamination and FRP debonding are predominant failure modes in FRP flexural strengthening that may be delayed or prevented by using FRP ...
