Slenderness effect on high strength concrete columns confined with GFRP wraps

67-74The paper presents the results of a study on the performance of glass fibre reinforced polymer (GFRP) wrapped high strength concrete (HSC) columns under uni-axial compression. The columns had slenderness ratios of 8, 16, 24 and 32. UDC GFRP was used with 3 mm and 5 mm thicknesses. The columns are tested under monotonic axial compressive loading up to failure. The deflections are noted for each load increment. The HSC columns with GFRP wrapping exhibited improved performance in terms of stress and ductility capacity
