Abstract: To improve the seismic resistance of a pier which needs the highest deformation capacity among the members of a bridge, two specimens constructed with steel fiber reinforced concrete and one specimen with normal concrete were loaded under reversed cyclic loading conditions. The results show that ductility factor was 8, and ultimate deformation capacity was 77 mm for the normal concrete specimen. The column constructed of steel fiber increased its deformation capacity, and ductility factor was 13, and ultimate deformation capacity was 111mm. This will be the effect of increasing the stress capacity after the peak stress at compression zone, due to the bridging effect of stress provided by steel fibers.
