Dimensionamento de dormente de concreto protendido utilizando método híbrido

Abstract

The present work presents a prestressed concrete sleeper sizing considering it a precast prestressed concrete beam, sizing method commonly learned in class, in conjunction with American Railway Engineering and Maintenance-of-Way Association’s (AREMA) method and ABNT NBR 11709:2015 recommendations. The theme has been chosen because it is not approached in the normal flow of the curricular organization chart of Faculdade de Engenharia Civil of Universidade de Uberlândia. And the object of study has been chosen for it being approached briefly along the graduation’s time. Being the principal objective of the work to serve as a reference base for future research and a bridge to link two curricular components. At the end of the work, it was concluded that the hybrid method can be used for the design of prestressed concrete sleepers. As the reinforcement found in the design, 8 wires CP 175 RB E 4.0 mm is enough to guarantee the safety and stability of the structure.
