Abstract: The application of externally post-tensioned segmental members is a very attractive solution compared with classical construction methods. The use of this solution results in smaller precast elements tied together by post-tensioned tendons, upbringing such advantages as fast and versatile construction, high quality control and lower overall cost. In this paper, a formulation based on the Finite Element Method is discussed. This formulation is used to numerically simulate the structural behavior of members composed of externally post-tensioned segments. These analyses not only allow serviceability limit states verifications when sections are fully compressed, but also allow verifications of ultimate limit states when joint openings and load transfers at the joints are considered. Additionally, to evaluate the accuracy of the numerical results of the computational model a comparison to experimental data from the literature is performed.
