Experimental study on high strength concrete columns with gfrp wraps under compression

This paper presents the results of an experimental study on high strength concrete columns with externally confined using GFRP wraps. A total of seven specimens of 150 mm diameter and 900 mm height were cast and tested. One specimen was used as reference and the remaining six specimens were wrapped with three GFRP materials having different thickness. The columns were tested under uni-axial compression up to failure. Necessary measurements were taken for each load increment. The HSC columns with GFRP wrapping exhibited improved performance in terms of strength, deformation ductility and energy absorption.
