Abstract

On the structural components, the use of a combination of two high-performance materials is a natural thing and It can not be avoided anymore, such a combination use of concrete which is accompanied by the use of high quality steel for transversal reinforcement that useful as a confinement reinforcement on the column or using for a polymer fiber as external confinement material on the column. Column is a very important structural component in ensuring a structure is not a total failure. In designing earthquake resistant structure, the column must have sufficient strength and ductility to behave ductile to absorb and emit seismic energy. Design faults and damage caused by the earthquake cause column have to enhance axial load capacity and flexural capacity. Carbon Fiber Reinforced Polymer (CFRP) is a new composite material for strengthening method that should be considered as an alternative, because of its light weight and high tensile strength. Confinement of externally circular concrete columns makes the column more strongly to the flexural and axial load because it has a very high tensile strength. The analysis performed shows an enhancement in compressive strength caused by FRP confinement and it’s also show that the increases of maximum axial load capacity are significant. Maximum axial load of confined concrete and confined concrete with tensile FRP tensile compared with unconfined concrete are 10.367% and 58.35 % higher respectively and the maximum axial load of confined concrete with full FRP is 91.18 % higher than the one of unconfined concrete for circular column.
