Abstract – Concrete is a commonly used building material. Poorly confined columns are recognized to behave in a brittle manner, exhibiting little deformation capacity. Increased loads, column deterioration, or seismic retrofit may require that additional confinement be provided to these columns to ensure adequate force and deformation capacity. The construction industry has considered using concrete confined by FRP. Applying composite materials to reinforced concrete has attracted much attention due to their lightness, rust resistance, high tensile strength and good flexibility. The material properties of composite materials greatly differ from those of steel.
Fiber reinforced polymer (FRP) composites are thin laminates that are externally bonded to structural members using epoxy adhesive. The FRP significantly increases the members load carrying capacity. These structural strengthening systems are made of high strength fibers (such as Armid, Glass and Carbon) embedded in a resin matrix. The resin protects the fibers, maintains their alignment, and distributes the loads evenly among them. FRP’s, which have been extensively used in industries such as aerospace, automotive, and sport equipment, are now becoming a mainstream technology for the structural upgrade of concrete structures.
