Fibers can play a major role in post cracking behavior of concrete members, because of their ability to bridge cracks and
distribute the stress across the crack. Addition of steel fibers in mortar and concrete can improve toughness of the
structural member and impart significant energy dissipation through slow pull out. However, steel fibers undergo plastic
deformation at low strain levels, and cannot regain their shape upon unloading. This is a major disadvantage in strong
cyclic loading conditions, such as those caused by earthquakes, where self-centering ability of the fibers is a desired
characteristic in addition to ductility of the reinforced cement concrete. Fibers made from an alternative material such as
shape memory alloy (SMA) could offer a scope for re-centering, thus improving performance especially after a severe
loading has occurred. In this study, the load-deformation characteristics of SMA fiber reinforced cement mortar beams
under cyclic loading conditions were investigated to assess the re-centering performance. This study involved
experiments on prismatic members, and related analysis for the assessment and prediction of re-centering. The
performances of NiTi fiber reinforced mortars are compared with mortars with same volume fraction of steel fibers.
Since re-entrant corners and beam columns joints are prone to failure during a strong ground motion, a study was
conducted to determine the behavior of these reinforced with NiTi fiber. Comparison is made with the results of steel
fiber reinforced cases. NiTi fibers showed significantly improved re-centering and energy dissipation characteristics
compared to the steel fibers.
