Verificação no estadio I e II e na ruptura de seções em concreto protendido

A computer program has been developed for analysis of the working stresses, the ultimate limit state and the ultimate fadigue state of a post-tensioned concrete section subjected to a bending moment and normal force. The program allows the analysis of sections for any age of the structure, as well as for applications of the prestressing operations and duct injections in various stages. It was taken into consideration the non-linearity, of the materials using the stress-elongation relations for the concrete and the steel proposed in the CEB-FIP codes from 1970. The ultimate limit analysis is done computing the safety index of the section in relation to the design forces due to permanent and variable loads. Some peculiarities about the interaction diagrams for the ultimate limit forces are discussed.
