DUCTILITY BEHAVIUOR OF HIGH STRENGTH CONCRETE COLUMNS WITH GFRP WRAPS

The paper presents the results of a study on the performance of Glass Fibre Reinforced Polymer (GFRP) wrapped high strength concrete columns under uni-axial compression. The columns had slenderness ratios of 8, 16, 24 and 32. Chopped Strand Mat GFRP was used with 3 mm and 5 mm thicknesses. The columns were tested under monotonic axial compressive loading up to failure. The deflections were noted for each load increment. The HSC columns with GFRP wrapping exhibited improved performance in terms of strength and ductility capacity.
