Flexural Performance of GFRP-Reinforced Concrete Beams with Shear Connectors and Web Stiffeners: Experimental and Numerical Assessment
Abstract: The The present study experimentally and numerically investigates the flexural performance of reinforced concrete beams incorporating Glass Fibre Reinforced Polymer (GFRP) reinforcement, mechanical shear connectors, and web stiffeners. Five beam configurations, namely CB-0, GB-1, GBS-2, GBW-3, and GBSW-4, were evaluated to determine their effects on load-carrying capacity, displacement, cracking behavior, strain development, energy absorption, and ductility. The conventional reinforced concrete beam CB-0 was considered the reference specimen. The experimental results …

A Review on Strengthening of RC Beam with GFRP Composite in Shear
Abstract: Glass fibre-reinforced polymer (GFRP) composites have emerged as an effective and lightweight technique for enhancing the shear performance of reinforced concrete (RC) beams, particularly in strengthening and rehabilitation applications. This review examines the influence of GFRP configuration on the shear behaviour, strength, cracking response, deformation, and failure mechanisms of strengthened RC beams. The discussion covers side-bonded, vertical and inclined GFRP strips, U-shaped wrapping, and complete wrapping configurations, with emphasis on …

Experimental and Numerical Assessment of Flexural Shear Behavior of RC Beams Enhanced using Hybrid CFRP–GFRP U-Wrap System
Abstract: This study examines the Reinforced Concrete beams strengthened in Flexural-shear using a hybrid Fibre Reinforced Polymer (FRP) system that combines carbon fibre reinforced polymer (CFRP) and glass fibre reinforced polymer (GFRP) in a U-wrap configuration. Six beams totally were made and the results were tested under 4 point bending moment using LVDT, in which three beams were of control beams without strengthening and another three externally wrapped using hybrid CFRP-GFRP …

Performance of GFRP Bars in Flexural Members: A Comparative Study with Metal Bars Using FEA and Experimental Study
Abstract: In recent years, GFRP bars have been introduced as a replacement for metal bars as reinforcement in flexural members. This study evaluates the use of GFRP bars as the main reinforcement in flexural members such as beams through computer simulations and experimental work. A 4-meter beam from a sample structure, analyzed as per IS 875 (1987) Part 2, was considered for the study. This beam was designed considering both metal …

Torsional Strengthening of RC Beam using Ferrocement Jacketing
Abstract: Due to the type of loading on the structure, it is generally known that there are four structural actions: axial force, shear, bending, and torsion. The reinforced concrete beams are said to be subjected to torsion, when the point of application of lateral loads does not coincides with shear center of the beam. These loads may be due to loading pattern or connection of beam. Torsional failure is typically seen …

Numerical Investigation on Structural Behavior of RC Beam-Column Joints: Beam Weak in Shear
Abstract: This study presents a numerical investigation on structural performance of reinforced concrete (RC) beam-column joints (BCJ) with beam weak in shear subjected to cyclic loading. Retrofitting techniques are explored, utilizing Glass Fiber Reinforced Polymer (GFRP) for shear strengthening, in accordance with ductile detailing standards outlined in IS 13920:2016. The column and beam elements are designed following the guidelines of IS 456:2000. Various specimen scales, including full-scale, 2/3-scale, and 1/3-scale specimens, …
