The use of headed bar is proposed for several practical applications instead of conventional reinforcing bars anchored by hooks and bends. In this paper, experimental investigation was conducted on behavior of concrete columns subjected to combined bending and axial loads with variables of the eccentricity ratio(e/h) and anchor type of transverse reinforcement. Test results show that the strength decrement due to the increase of the eccentricity could be diminished by head bars for confining .
