dc.description.abstractThe structural evaluation of heavy haul railroad tracks has always been sought by engineers and researchers to achieve better-performing structures to satisfy the constant need for higher transportation capacity. Physical models are implemented in the laboratory for mechanical behavior assessment of railroad track components in terms of stresses, strains, and displacements, to assist in the design, maintenance, and rehabilitation procedures. Several computational tools, such as numerical models using Finite Element Method (FEM), can also be used for this purpose. This paper aims to contribute to the development of a layered structure of a full-scale facility to simulate a railroad track in the laboratory. This introductory study was conducted by developing 3D FEM numerical models to evaluate the mechanical behavior of a layered railroad track structure in the field and laboratory. Numerical results are compared with data from field monitoring for calibration, considering a loading scenario of 32 tons/axle. The AREMA load model was applied to calculate the load impact factor to simulate a dynamic load in the numerical model. The results showed that the proposed methodology supports the idealization and development of a full-scale laboratory test to simulate a railroad track structure.pt_BR
