Carbon fiber jacketing is an efficient technique for increasing the strength and strain capacity of concrete circular square section columns subjected to axial load, although confinement efficiency decreases rectangular cross-section members. The research project BIA 2016-80310-P includes experimental program on intermediate-size plain specimens strengthened with carbon jackets, mostly cross-se...

fi ber reinforced plastic (FRP) re. nforcement is one of the most promising new developments for concrete structures. FRP reinforcing elements provide lighter, easier to assemble, and more durable structures that are free of the deterioration caused by corrosion of steel. FRPs consist of synthetic or organic highstrength fibers, most of which are impregnated with a resin matrix. They are availa...

Experimental and numerical investigations on the retrofitting of half-scale wall-like reinforced concrete (RC) columns were conducted. The axial compressive behavior control un-strengthened RC column (having a section aspect ratio four) was compared with strengthened columns. by employing external confinement through fiber-reinforced polymer (FRP) wraps and/or steel/FRP strips with/without modi...

Strengthening of reinforced concrete structures using FRP has emerged as a potential solution to the problems associated with civil infrastructure. Many researchers have reported significant increases in strength and stiffness of concrete structures strengthened with FRP. Nevertheless, possible brittle failures of the strengthened system due to delamination of the FRP strips and/or sheets could...

As a preliminary study for the erection of floating structures using high performance concrete, this paper examines the bond characteristics between concrete and the reinforcing bar. Since the floating structure is constructed in aquatic environment, corrosion of the reinforcing steel is likely to develop more prematurely than in onshore structure in case of concrete cracking. A solution to thi...

The use of Glass Fibre Reinforced Polymer (GFRP) bars is considered an alternative option in reinforcing concrete structures instead of conventional steel bars especially in harsh severe environments, due to their mechanical properties and physical characteristics. GFRP bars offer many advantages over steel counterparts such as corrosion resistance, high tensile strength, low weight and electro...
