CFRP is an alternative technique for cracking control of high-chloride reinforced concrete (RC) beams. This research, therefore, investigates the strength performance and failure mode behaviour RC beams incorporated with sea sand bonded externally carbon fibre polymer (CFRP) plate. Sea used as a 100% replacement fine aggregate. Three batches were carried out in this including beam (no neither C...

This paper reported the very earliest experimental and analytical studies on bonded Prestressed CFRP tendon enhanced Steel Reinforced Concrete (PSRC) members under eccentric tensile loads . Eight PSRC were tested monotonic loading, three (SRC) simultaneously for comparison. The load–deflection relationship, strain distributions as well crack propagation fracture of concrete investigated experim...

This paper presents experimental research on structural behaviour of normal and recycled aggregate concrete filled steel tube (RACFT) columns externally strengthened with carbon fibre reinforced polymer (CFRP) sheets and subjected to axial loading. A total of 22 specimens were tested to investigate the influence of the following variables: (1) tube configurations, circular or square, solid or h...

External bonding of carbon fiber sheets has become a popular technique for strengthening concrete structures all over the world. Epoxy adhesive, which is used to bond the carbon fiber sheets and concrete, deteriorates rapidly when being exposed to high temperatures. This paper presents a high-temperature-resistant modified magnesia-phosphate cement (MPC) with the compressive strength that does ...

Abstract The paper reports the analytical investigation in Multi-storey building located seismic zone III. This is considered as moderate-damage risk per Indian Codal provision and thirty percent of India falls this category. To improve performance, externally bonded FRP strengthening techniques are adopted to deficient beam columns, paper, analysis carried out with without lateral resisting sy...

1.1 Background Fibre Reinforced Polymers (FRP’s) have seen active use for strengthening applications in construction since the late 1980’s. They are now securely placed to replace the ageing technologies used in the commonly termed, ‘traditional methods’ of strengthening, which have customarily resulted in an increased cross-section size with the provision of additional reinforced concrete, or ...

In this study, twenty glass fiber reinforced polymer (GFRP) reinforced concrete specimens were modelled using finite element method to predict the effect of GFRP compressive bars on the flexural strength and ductility of GFRP reinforced concrete beams. Also, the contribution of GFRP longitudinal rebars to the load-carrying capacity of reinforced concrete columns is determined. The concrete elas...

Bonded patches are widely used in several industry sectors for repairing damaged plates, cracks metallic structures, and reinforcement of structures. Composite have optimal properties such as high strength-to-weight ratio, easiness being applied, flexibility. Due to recent rapid growth the aerospace industry, analyses adhesively bonded applicable cracked structures become great significance. In...
