Abstract: The excellent ductility, energy dissipation capacity, and damage tolerance exhibited by fiber reinforced cement composites make them attractive materials for use in critical regions of earthquake-resistant structures. In this paper, a summary of relevant research conducted during the last twenty five years on the use of fiber cementitious composites in structural members subjected to displacement reversals is given. Typical applications include beam-column connections, plastic hinge regions of flexural members, structural walls, coupling beams, connections for precast construction, and seismic repair/retrofit of structures. Based on the results from a large number of experimental programs, the use of fiber reinforced cement composites has been shown to increase strength, displacement capacity, energy dissipation and damage tolerance in structural members. In addition, structural elements constructed with these advanced materials generally exhibit a lower rate of strength and stiffness deterioration compared to reinforced concrete members under displacement reversals. Further, comparable or even enhanced behavior has been observed in members with fiber reinforced materials and significantly less reinforcement detailing compared to well detailed reinforced concrete members. Areas for future research, as well as strategies to foster the use of fiber reinforced cement composites in seismic-resistant structures, are identified.
