This research provides a method that can be conveniently and easily to apply the prestressing force to concrete structures incorporating shape memory alloy fibers. For this, discrete shape memory alloy fibers were manufactured to be mixed with cement mortar. Then shape memory effect was generated to evaluate uplift displacements at the mid-span of the mortar beams with increasing fiber volume fractions.
