Strength and Ductility of GFRP Wrapped Corrosion-Damaged Concrete Columns

This paper presents the results of an experimental investigation to evaluate the effects of GFRP wrapping on the structural behaviour of corrosion damaged concrete columns of size 150 mm x 900 mm. The columns were subjected to different degrees of accelerated corrosion. The damaged columns were wrapped with GFRP. The test results show a marked enhancement in ultimate strength by 30% and ductility by 110%. The strength and ductility of the GFRP confined corrosion-damaged columns increase with increasing wrap thickness.
