Behaviour of reinforced concrete columns wrapped with fibre reinforced polymer under eccentric loads

This paper presents the influence of fi bre reinforced polymer (FRP) on concrete columns' carrying capacity of concentric and eccentric loads. Twelve high-strength reinforced concrete (RC) columns were cast and tested. The specimens were in three groups: RC; RC wrapped with three layers of horizontal carbon fibre reinforced polymer (CFRP); and RC wrapped with three layers of horizontal and three layers of vertical CFRP. From each group, three specimens were tested as columns. The fourth specimen was tested as a beam. Results of this study showed that FRP is an effective material for strengthening under eccentric loads.
