Experimental Study on the Bearing Capacity and Ductility of High Strength Concrete Columns Wrapped with CFRP Cloth

Abstract:

By the axial compression tests on a total of 19 high strength concrete columns wrapped with CFRP cloth, the influence of shape section and different layers on the axial compressive strength and ductility is studied. The experimental results indicated: high strength concrete columns wrapped with CFRP in increasing the bearing capacity and ductility of concrete columns is still valid, its effect on the improvement of ductility is much greater than its capacity.
