Flexural Performance of RC Beams Strengthened with Longitudinal SMA

Abstract

Nowadays, new materials have appeared that have played an important role to improve the structural behavior of RC members. the flexural performance of shape memory alloys (SMA) of RC beams will be studied. Many specimens with different parameters with longitudinal rebars of SMA and the other without SMA will be presented, and the specimens will be analyzed using programs that based on Finite Element Method (FEM) such as Abaqus program. A parametric study will be conducted using the following parameters: the diameter of rebars, and the distance between the loads on flexural strengthening for RC beams by using longitudinal rebar of SMA and steel, the results will be compared to experimental literature, additionally, the relationship between loads and displacement for RC beams will be drawn, as well as the relation between ductility and flexural strengthening.
