Análise comparativa de métodos de distribuição transversal de carga em pontes em viga de madeira lamelada colada

Abstract

One of the objectives of a structural design is, in addition to guaranteeing the safety and stability of the structure, optimizing scaling in order to guarantee greater savings in the construction, for that it is necessary to know which actions are applied in the structure and the appropriate combinations. However, the actions applied to the structures are not equally divided in all its parts and it is up to the engineer to define the most critical combinations to the structure and how the loads are distributed over it. This work presents the study of the transverse load distribution in the cross section of a glulam bridge model with multiple stringers using both analytical and computational models. The most usual methods in bridge structures were verified: Engesser-Courbon, Leonhardt, Fauchart and Guyon-Massonet, these methods were then compared with the finite element computational models (FEM), verifying their convergences and the influence that the number of diaphragms cause in the load distribution by the stringers.
