Abstract In order to investigate the seismic behavior of earthquake-damaged GFRP Glass Fiber Reinforced
��
Polymer tubed reinforced concrete bridge piers repaired with wrapped CFRP carbon fiber reinforced polymer or
�,
plastics sheets four GFRP tubed RC bridge piers repaired with wrapped CFRP sheets were tested under repeat low

cyclic load. The hysteresis loops skeleton curves ductility and energy dissipation ability of the repaired RC bridge
piers pared with those of the original piers. Research show that the bearing capacity and ductility of the
repaired bridge piers can be restored or even improved.
