In its calculation process, it is necessary to verify the prestressing losses, which are inherent to this technology, looking for the best use of materials and economic structures. Therefore, it is necessary to use computational tools to optimize the calculation steps. The AutoLISP programming, a language recognized by AutoCAD, and very employed by designers, allows programming of the equations provided by NBR 6118 for prestressing losses calculation and draws the strucutural element and the prestressing losses graphics. Two examples are shown to validate the results of the program. The results obtained by the program are compared to the values obtained manually. The results show that the program is effective in the calculation of prestressing losses, for active-active and active- passive anchorages, as well as the graphs for immediate progressive losses. Another positive aspect of using the program is the use of more elaborate formulation for progressive losses calculation provided by NBR 6118, resulting in more precise values.Acesso AbertoAnálise estrutural (Engenharia)Concreto protendidoAutoLISP (Linguagem de programação de computador)CNPQ::ENGENHARIAS::ENGENHARIA CIVIL::ESTRUTURAS::ESTRUTURAS DE CONCRETOTrabalho de Curso - Graduação - Monografia
