Summary: Software simulation is prominent in civil construction and contributes to the feasibility and use of new materials, such as wood. The numerical software model is based on the development of mathematical models that explain the characteristics and behavior of the materials, this facilitates the analysis and increases the safety of the construction, mainly in the mixed projects, which present a great potential of civil construction. The use of mixed bridges of wood and concrete, for example, improves the load capacity and mechanical strength of the structure and reduces construction costs, being one of the best solutions in rural areas. But, in Brazil, this type of structure is not yet widely used, due to the lack of specific standards and anatomical complexity of the wood. The objective was to promote the structural calculation of wood and concrete projects, using the finite element method, modeled in the structural analysis program SAP 2000, to evaluate the behavior of beams. For this, information was extracted from the literature to use the computer program, which made the simulations of displacement and stresses in three models with different spaces between a core and a table of the beams, which had or not connectors (steel pins). After adjusting and analyzing the simulated models, he validated the computational results by comparing them with experimental data and specific standards. In conclusion, the numerical simulation enabled the analysis of the behavior of the views, satisfactory results were observed in the models with connectors, which possibly was the element responsible for the best performance of wood and concrete.
