Fiber reinforced polymer (FRP) composite materials have been studied and applied to reinforced concrete (RC) structures for strengthening or seismic retrofit for many years. This research is related to using FRP composites in new bridge structures. Capacity degradation in RC components of existing bridges occurs in harsh weather conditions when corroded steel reinforcement expands, which causes subsequent strength losses in concrete through the development of cracking and spalling. After significant earthquake events, RC structures undergo substantial residual displacement, which may cause instability and prevent the continued use of these structures.
