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 ...

This research investigates the behavior of extended reinforced concrete beams that have been enhanced using CFRP at extension points. Five with measurements 2500 mm in length, 150mm width, and 260mm height were built different types. The studied cases included varied strengthening schemes for splice joints. findings conclude inclusion horizontal stirrups on complete top beam produced comparable...

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...
