Experimental 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 کاملMechanical Model to simulate the NSM FRP strips shear strength contribution to RC beams
A three dimensional mechanical model has been recently developed to simulate the Near Surface Mounted (NSM) Fibre Reinforced Polymer (FRP) strips shear strength contribution to Reinforced Concrete (RC) beams throughout the entire loading process, as function of the Critical Diagonal Crack (CDC) opening angle. It was developed by fulfilling equilibrium, kinematic compatibility and constitutive l...
متن کاملProposed Design Procedure of Nsm Frp Reinforcement for Flexural and Shear Strengthening of Rc Beams
Near-surface mounted (NSM) fiber-reinforced polymer (FRP) reinforcement has been found to perform efficiently as a flexural/shear strengthening technology for reinforced concrete (RC) members, while offering some additional practical advantages with respect to the most widespread technique of externally bonded laminates. This paper presents a design procedure for flexural and shear strengthenin...
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 کاملStrengthening of RC Beams with Large Openings in Shear by CFRP Laminates: 2D Nonlinear FE Analysis
To date, theoretical studies concerning the Carbon Fiber Reinforced Polymer (CFRP) strengthening of RC beams with openings have been rather limited. In addition, various numerical analyses presented so far have effectively simulated the behaviour of solid beam strengthened by FRP material. In this paper, a two dimensional nonlinear finite element analysis is presented to validate against the la...
