Abstract :

This paper presents the results of an experimental investigation of the axial behavior of small scale square reinforced concrete columns with fiber reinforced polymer (FRP) bars, as a solution to overcome the corrosion problems, where this material represents a relatively new technology; therefore much research is needed to determine its characteristics and gain confidence to be accepted by engineers for practical application.A series of 8-column was tested in a vertical position and under compressive axial static loading. Where all columns had the same dimensions 250*250mm and 1250mm height, main reinforcement 4#12mm, 6#12mm, and 8#12mm, the transverse reinforcement was ø6@120mm closed stirrups along columnThe major parameters included in this research were the main reinforcement ratios, the main reinforcement types, the transverse reinforcement ratios in the column, and the charac-teristic strength of concreteResults from a series of tests on small-scale specimens showed that increasing main reinforcement, transverse reinforcement ratios in the column ends and increasing characteris-tic strength of concrete have a significant effect on the behavior of reinforced concrete col-umns with GFRP.
