FLEXURAL STRENGTHENING OF RC BEAMS USING FERROCEMENT LAMINATES
… ferrocement laminate, the increase in ultimate flexural capacity of the strengthened beams, and the shear stress at the original beam/ferrocement laminate interface were derived and compared with the experimental results and available test data from other studies. The results show that the …

Textile fine grined mortar containing palm oil fuel ash as a partial cement replacement for flexural strengthening on reinforced concrete beams
… Palm Oil Fuel Ash (TFGM-POFA) as an upgrading strengthening method of concrete structure. Fine Grained Mortar inclusion POFA (FGM-POFA) with size 40 mm x 40 mm x 160 mm consist of fine sand less than 1 mm, ordinary Portland cement (OPC) and POFA as a partial OPC replacement. Flexural and …

SIGNIFICANCE OF U-WRAP FRP SHEAR STRENGTHENING ON FLEXURAL BEHAVIOR OF RC BEAMS STRENGTHENED USING NEAR SURFACE MOUNTED FRP BARS
… to investigate the significance of U-wrap shear strengthening on the flexural behavior of Near Surface Mounted (NSM) Fiber Reinforced Polymers (FRP) strengthened Reinforced Concrete (RC) beams. It is well-known that the performance of NSM-FRP technique is strongly dependent on bond performance …

A fracture-based approach to understanding debonding in FRP bonded structural members
… with various configurations of shear and/or flexural strengthening and anchorage conditions in four evolutionary experimental stages involving both monotonic and cyclic loading. A dramatic improvement in the debonding behavior and performance of the beams was observed with shear strengthening …

A New CFRP-UHPC System for Strengthening Reinforced Concrete T-Beams
… (FRP) was introduced to the construction field, strengthening of reinforced concrete beams using FRP laminates became a common repair and retrofit technique. Traditionally, Reinforced Concrete (RC) beams are strengthened by adhering FRP laminates to the tension side of the beam to work as an …

STRUCTURAL RETROFITTING OF CONCRETE BEAMS USING FRP - Debonding Issues
… of the beam increases for both shear and flexural strengthening. The result also showed that the FRP to concrete width ratio and the stiffness of FRP affect the failure mode of retrofitted beams. The maximum load increases with increased width ratio. Increased FRP stiffness increases the …

Experimental Investigations of Residual Strength and Repaired Strength of Corrosion Damaged Prestressed Bridge Beams
… were then tested in the lab to determine their flexural strength. Following testing, samples of strands were removed and tested to determine their tensile properties while cores were taken to determine compressive strength. Powdered concrete samples were removed to perform chloride concentration …

Performance Evaluation of RC Flexural Elements Strengthened by Advanced Composites
The flexural performance of composite systems made of reinforced concrete, Fibre Reinforced Polymers (FRPs) and adhesives was studied during the current research. The experimental investigation was principally concentrated on the potential use of Kevlar® 49 (aramid fibre) for RC beam strengthening. …
