Abstract
Because polymer-composite reinforcements are a new material in construction, the possibilities of their use in load-bearing structures, including concrete beams, are somewhat limited by existing regulations. The research work implemented in this article is to study their strength and stiffness in cases where steel reinforcement is in the tensile zone and composite polymer reinforcement is in the compressive zone of concrete. Concrete beams with combined reinforcement are the object of the study, and the study of the stress-deformation state is its subject. The behavior of concrete beams with combined reinforcement under static load was studied. Considering the nonlinear properties of materials in the finite element method, their stress-strain states were investigated. A 3D beam model was created using the ANSYS Workbench 2022R1, and 3 series of samples were chosen and compared with hand calculations. The behavior of concrete beams with metal and composite reinforcement was carried out using numerical analysis. Also, the study’s results show that the role of the reinforcement installed in the compressive zone of the beam is better than the performance of the beam without the reinforcement installed in the compressive zone. Although the failure starts with the rebar in the tensile zone, the rebar installation in the compression zone shows an increase in the bearing capacity and stiffness of the beam.
