There is a growing need for the rehabilitation, repair, and upgrading of concrete structures such as bridges and buildings. The repair or rehabilitation of reinforced concrete structures often offers a lower cost alternative to rebuilding, and it is traditionally achieved by bonding steel plates to the tensile face of a reinforced concrete member. The shear strength can be enhanced with plates ...

This paper presents a study of the shear capacity reinforced concrete (RC) beams strengthened in with externally bonded (EB) fiber polymer (FRP) composites, based on performance existing published tests. The main objective this is to create comprehensive overview different strengthening configurations and failure modes observed experimental In addition, influence following parameters efficiency...

Carbon fiber reinforced polymer (CFRP) sheets are externally bonded to reinforced concrete (RC) members to provide additional strength such as flexural, shear, etc. It has been widely accepted that carbon fiber reinforced polymers (CFRPs) can be used effectively to strengthen reinforced concrete (RC) members. This paper is intended to study and use externally bonded CFRP strips to repair and st...

Both the flexural and shear strengths of reinforced concrete (RC) beams can be substantially enhanced using externally bonded fibre reinforced polymer (FRP) composites. Failures of such FRP-strengthened RC beams often occur by debonding of the FRP plate from the RC beam in a number of forms. Despite numerous theoretical and experimental studies on debonding failures of FRP-strengthened RC beams...

Corrosion of steel reinforcement is one of the main durability problems facing reinforced concrete infrastructures worldwide. This paper will summarize the results of a multi-phase experimental program undertaken at the University of Waterloo to investigate the viability of using externally bonded fiber reinforced polymer (FRP) laminates to rehabilitate corrosion-damaged reinforced concrete bea...

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...

Abstract Little is known about the behavior and durability of strengthening systems applied on concrete substrata possible loss performance due to degradation intervening materials by structure’s natural aging process exposure externally strengthened elements aggressive environments. In this context, present work presents an experimental analysis reinforced beams with Carbon Fiber Reinforced Po...

Advances in the fields of polymers and composites have resulted in a major development of high strength fibre reinforced polymers (FRP). These materials offer great potential for cost-effective retrofitting of concrete structures. In response to the growing need for concrete repair and rehabilitation, an experimental program was conducted at the University of Manitoba in Winnipeg, Manitoba, Can...

This paper aims to introduce the content of Annex J “Strengthening Existing Concrete Structures with CFRP” Eurocode 2 [1]. is first time that design adhesively bonded reinforcement CFRP has been introduced in European regulations through an informative annex. considers two different strengthening techniques: externally (EBR) consists bonding strips or sheets surface concrete elements, and near ...
