The flexural resistance of reinforced concrete (RC) members such as beams and slabs can be enhanced by bonding fibre-reinforced polymer (FRP) composite plates to their tension face. The effectiveness of the strengthening can be compromised though by

This paper presents a numerical study that investigates the performance of reinforced concrete (RC) T-beams externally strengthened with carbon fibre reinforced polymer (CFRP) plates when subjected to fire loading. A finite element (FE) model is deve

A detailed 3D time domain transient thermal-stress finite element analysis is performed to study the heat transfer mechanism within a CFRP strengthened reinforced concrete beam for fire conditions initiating at the top of the beam. This loading scena

The use of FRP bars to reinforce concrete structures has received a great deal of attention in recent years. It is considered as one of the most prominent solutions that may overcome the corrosion deficiency of reinforcing steel bars under long-term

The external fiber reinforced polymer (FRP) flexural and shear strengthening of reinforced concrete beams is a well-established technique for structural rehabilitation and upgrade. In the present work, an analytical solution is developed for the load

The use of polymer adhesives during the strengthening of 30-year-old prestressed concrete bridge girders is described. The single-T–shaped specimens strengthened in this study were saw-cut from prestressed concrete double-T girders that had been re

The second order differential equation of interface shear is formulated for fiber-reinforced polymer-strengthened beams using beam theory with a shear deformable adhesive layer. The solution of the boundary value problem is obtained in closed form an

SP-264: Serviceability of Concrete Members Reinforced with Internal/External FRP Reinforcement.
This paper will discuss how the use of externally bonded FRP plates and sheets has been established as an effective mean to strengthen concrete beams in flexure and shear. Several investigators have shown that the direct use of Branson equation does

The need to upgrade the capacity of structural members is growing due to the aging infrastructure elements and the expanding volume of traffic. The use of external fiber-reinforced polymer plates bonded to the tensile face of beams has proven to be e
