Frp Composites for Shear Strengthening of Rc Beams
ABSTRACT Fiber Reinforced Polymer (FRP) composite systems can be used for shear strengthening of reinforced concrete (RC) members. The present study investigated the shear performance and the modes of failure of simply supported RC T-beams externally strengthened in shear with FRP composites. Two different FRP-based strengthening systems were investigated, namely, externally bonded FRP sheets a...
متن کاملStrut-and-Tie Method for Prediction of Ultimate Shear Capacity of Shear-Strengthened RC deep beams with FRP
The main objective of this study is to propose the Strut-and-Tie method (STM) to predict the shear capacity of simply supported RC deep beams shear-strengthened with carbon fiber reinforced polymers (CFRP). It is assumed that, the total carried shear force by shear-strengthened RC deep beam provided by three independent resistance, namely diagonal concrete strut due to Strut-and-tie mechanism, ...
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 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 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...
