The Both bonded and unbonded prestressing tendons may be used to reinforce post-tensioned (PT) concrete members. The binding state of tendons may have an impact on how well different types of PT concrete elements function in flexural and shear loads. Inverted-U shape reinforcement was used experimentally to enhance the behavior of different structural elements. The obtained results confirmed the proposed model’s accuracy for both PT slabs and beams (bonded, and unbonded). This study's major goal is to compare numerically PT concrete slabs provided with inverted-U shape reinforcement with the two different tendon systems and evaluate their performances due to applying punching shear load. To do this, the PT slab that has already been tested is reexamined numerically. By using, a nonlinear finite element, the results were carried out utilizing visualization tools. For a better study of the behavior of bonded and unbonded PT slabs, the obtained numerical results, and the previous experimental one are compared. Good correlations are shown.
