Abstract
This paper presents an experimental investigation on the behaviour of concrete columns reinforced with glass fibre reinforced polymers GFRP bars under concentric and eccentric loads. Six RC column specimens have been considered in the experimental tests with a cross section dimension of (135 mm × 135mm) at the middle portion of columns and (250 mm × 135 mm) (width ×depth) at the corbel with a total length of 1150 mm with the length between corbels (middle part) was 710 mm. Three specimens have been represented the reference specimens which are reinforced with steel bars and the other three were reinforced with GFRP bars. Tow variables have been considered in the experimental tests: the type of reinforcement (GFRP and steel) and the eccentricity ratio (e/h). All columns have been subjected to different values of eccentricity ratio (e/h): 0, 0.5, and 1. It has been concluded that the ultimate load capacity of columns reinforced with GFRP bars decreases by about 27.13% and 94.67% compared to columns reinforced with steel bars under eccentricity ratios (e/h=0) and (e/h =0.5), respectively. Whereas, ultimate load increases by about (4.79%) for the columns reinforced with GFRP bars compared to columns reinforced with steel bars at eccentricity ratios (e/h=1). The result have also shown that all specimens that have been subjected to eccentricity ratio (e/h > 0) failed by compression failure.
