Fiber-reinforced polymer (FRP) composites are widely employed as externally bonded reinforcement (EBR) systems for strengthening reinforced concrete members. More recently, a new technique, referred to on grooves (EBROG), has been proposed, which is based using number of throughout the substrate enhance bond strength between FRP composite and concrete. This study investigates influence groove d...

In most cases, openings are made in the Web of deep beams for installations to pass through. These members require be strengthened since reduce load-bearing capacity. This study utilizes carbon fiber-reinforced polymer (CFRP) composites and steel protective frames (SPF) as strengthening configurations reinforced concrete (RC) improve strength lost due square openings. To this end, eleven specim...

Strengthening reinforced concrete (RC) beams and slabs with prestressed carbon fiber-reinforced polymer (CFRP) composites is of high interest since the FRP material can be used more efficiently. Developing a non-mechanical strengthening system entails evaluating bond resistance to substrate. To increase CFRP strips substrate, new method called externally bonded reinforcement on grooves (EBROG) ...

In reinforced concrete design, there are situations where transfer of shear across a specific plane needs to be considered. Examples of such situation include corbels, bearing shoes, ledger beam bearing, and a host of connection between precast concrete elements. In this study, the shear transfer behavior of reinforced concrete is investigated experimentally by conducting test on 6 precracked p...

The use of externally bonded Steel-Reinforced Polymer (SRP) and Steel Reinforced Grout (SRG) composites is a promising new technology for increasing the flexural and shear capacities of reinforced concrete (RC) members. The reinforcement system in these composites is a sheet made up of unidirectional cords consisting of tightly wound ultra high strength steel wires. The reinforcement can be mol...

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...
