Desenvolvimento de software para dimensionamento da armadura longitudinal de vigas em concreto protendido

Abstract

With the advent and use of new technologies used in civil construction, such as the case of non-adherent post-tensioning, the calculation processes ended up being increasingly sophisticated, with the need for more accurate, quick and reliable calculations. Therefore, the present work presents the development of free software capable of facilitating the understanding and making the design process of a nonadhering prestressed beam, faster and more reliable. For this, the program follows the recommendations of NBR 6118:2014, it has a nice graphic interface, being divided into tabs. In addition, the program presents the results obtained during the calculation process, such as the checks in the strength limit states and serviceability limit states applied, cable tracing, losses and prestressing efforts, for better analysis of the structural element. In order to validate the developed tool, two examples were made and compared to the bibliography. In them, the software presents a convergence of 100% for the dimensioning of the active reinforcement, whereas for the passive reinforcement to compare, there were differences, mainly due to the regulations in force at the time. In addition, the efforts found by the program also differ, but not by implication. The project also aims at studies in the area, facilitating the understanding of the subject and assisting teachers in undergraduate courses.
