Behaviour Of Cfrp Wrapped Square Rc Columns Under Eccentric Loading, Xu Lei, Thong Minh Pham, Muhammad N. Hadi
Faculty of Engineering and Information Sciences - Papers: Part A
Fibre Reinforced Polymer (FRP) is an excellent material to strengthen existing structures. However, the confinement efficiency of FRP - confined square columns is relatively low compared to circular columns due to stress concentration at the sharp corners. This paper presents a new techniqu e aimed to maximise the efficiency of FRP confinement for square concrete columns : circularisation using segmental circular concrete covers . Sixteen square reinforced concrete columns were cast. Four were used as a reference group; four were rounded 20 mm at each corner and wrapped with three layers of CFRP simulating the conventional methods; the rest eight …
