Resumo: | Due to its advantages, Prestressed Concrete has been used as a structural element in many buildings worldwide. In order to overcome large spans, limiting the formation of cracks, its application can be visualized, for example, in bridges, viaducts, and building slabs. These structures are executed by stretching steel cables with a subsequent release, introducing compressive stresses in the concrete. However, during this process, stress losses occur in the active reinforcement, requiring forecast by the designers. Quantifying these losses in certain cases is a long and iterative process. The present work aimed to present the computational implementation of an alternative method for determining the loss due to deformation of the anchorage in post-traction. In order to prove its effectiveness, this method was contrasted with two conventional methodologies established in the literature. To this end, two models of beams of the same cross-section were simulated, however, with different spans and cable paths. Both proposed simulations aimed to cover all possible situations for the development of prestressing stress along with the tensioned cables. The alternative method showed minor differences in all measurements compared to the conventional methods, proving its effectiveness. Furthermore, the computational tool, entitled vProt, proved to be reliable in the two proposed simulations, allowing its use in the elaboration and verification of structural projects. |

Due to its advantages, Prestressed Concrete has been used as a structural element in many buildings worldwide. In order to overcome large spans, limiting the formation of cracks, its application can be visualized, for example, in bridges, viaducts, and building slabs. These structures are executed by stretching steel cables with a subsequent release, introducing compressive stresses in the concrete. However, during this process, stress losses occur in the active reinforcement, requiring forecast by the designers. Quantifying these losses in certain cases is a long and iterative process. The present work aimed to present the computational implementation of an alternative method for determining the loss due to deformation of the anchorage in post-traction. In order to prove its effectiveness, this method was contrasted with two conventional methodologies established in the literature. To this end, two models of beams of the same cross-section were simulated, however, with different spans and cable paths. Both proposed simulations aimed to cover all possible situations for the development of prestressing stress along with the tensioned cables. The alternative method showed minor differences in all measurements compared to the conventional methods, proving its effectiveness. Furthermore, the computational tool, entitled vProt, proved to be reliable in the two proposed simulations, allowing its use in the elaboration and verification of structural projects. |
