BEHAVIOR OF SHORT CONCRETE COLUMNS REINFORCED BY CFRP BARS AND SUBJECTED TO ECCENTRIC LOAD

This paper focused to study the behavior of short concrete column reinforced by CFRP bars and subjected to eccentric axial load. It was based on t en concrete columns with normal concrete. All columns were identical in size and the nominal dimensions. The model dimensions selected in the present investigation was a square section of 140*140mm and a total length of 820mm. The length between corbels (middle portion) was 400mm, for eccentric loaded columns, variable values of eccentricity ( e ) were studied herein. Three of columns were cast as control specimens or for the purpose of comparison, one without reinforcement and two with longitudinal steel reinforcement, the other specimens were as longitudinal reinforced by CFRP bars.
