Strengthening of defected beam–column joints using CFRP
This paper presents an experimental study for the structural performance of reinforced concrete (RC) exterior beam-column joints rehabilitated using carbon-fiber-reinforced polymer (CFRP). The present experimental program consists of testing 10 half-scale specimens divided into three groups covering three possible defects in addition to an adequately detailed control specimen. The considered de...
متن کاملExperimental and Theoretical Investigation on Shear Strengthening of RC Precraced Continuous T-beams Using CFRP Strips
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...
متن کاملAn Experimental Study on Shear Strengthening of RC Lightweight Deep Beams Using CFRP
. This paper presents the results of an experimental investigation on shear strength enhancement of reinforced concrete deep beams externally reinforced with fiber reinforced polymer (FRP) composites. A total of six deep beam specimens of two different classes, as-built (unstrengthened) and retrofitted were tested in the experimental evaluation program. Two composite systems namely carbon/epoxy...
متن کاملBond Behavior of a CFRP Strengthening System for Steel Structures
This paper summarizes an experimental program supported by an analytical modeling study undertaken to investigate the bond behavior of carbon fiber reinforced polymer (CFRP) materials used for strengthening steel structures. The experimental program consisted of three double-lap shear coupon tests and five large-scale beam tests. Different methods to reduce the bond stress concentrations near t...
متن کاملReview on bonding techniques of CFRP in strengthening concrete structures
Selecting appropriate bonding technique is crucial for strengthening and repairing concrete structures as different bonding techniques have different performances. A state-of–the-art review of different bonding techniques that is epoxy bonding technique, prestressed strengthening technique, unbonded anchored technique/mechanically fastened technique using CFRP is dealt and the corresponding adv...
