Monografia (Especialização) - Curso de Engenharia Civil, Departamento de Engenharia Civil, Universidade Federal do Rio Grande do Norte, Natal, 2016.https://repositorio.ufrn.br/handle/123456789/40824The goal of this paper is to evaluate the structural behavior of beams of hyperstatic reinforced concrete bridges subjected by static and cyclic loads, represented by design vehicles. For that matter, four models of bridges are proposed, each one with different proportion between cantilever and span. Taking into account the standards’ recommendations, the designs on flexural and the fatigue analysis are done. The results show that the mean reinforcement fatigue factor increases with the growth of the cantilever/span proportion. The best proportion, with the lowest mean reinforcement area ratio, according to the NBR, and the second lowest mean fatigue factor, is 1/4. From the comparisons it is stated that the Eurocode is more conservative than the NBR, on terms of design and fatigue.openAccessfadigadimensionamentoNBREurocodebachelorThesisCNPQ::ENGENHARIAS::ENGENHARIA CIVIL::ESTRUTURAS::ESTRUTURAS DE CONCRETO
