Abstract
The paper deals with strengthening of the reinforced concrete beam by shape memory alloy at the place of maximum loading and deformation. A structural analysis is performed using FEM to study the behavior of the beam reinforced by steel and shape memory alloys under 3- and 4-point bending. The elasticity of the reinforced concrete beam with NiTi rods slightly increase and depends on loading type. It was revealed, that under the bending in the beam reinforced by shape memory alloy the residual deflection decreases in comparison with traditional reinforcement.
