Experimental Study on Seismic Performance of Fiber Reinforced Concrete Pier

Abstract

In order to study the seismic performance of fiber reinforced concrete pier, four scaled piers whose material is reinforced concrete (RC), carbon fiber reinforced concrete (CFRC), polypropylene fiber reinforced concrete (PPFRC) and hybrid fiber reinforced concrete (HFRC) respectively have been tested under dynamic and static hydraulic servo testing system. The hysteretic curves, dissipating capability, residual deformation and ductility of each specimen are compared and studied. Experimental results indicate that the residual deformation of specimen PPFRC is not as good as CFRC, but it has well ductility. The specimen HFRC possesses the characteristic of small residual deformation and well performance of material dissipation and restoration ability. The dissipating ability of HFRC, CFRC and PPFRC are increase by 12%, 8% and 6% respectively as compared with RC. The HFRC has the best seismic performance due to small residual deformation, good restoration ability and ductility.
