%X this paper shows the strategy used in the numeric modeling of a composite specimen of wood and concrete, with metallic connection system, with applied cyclical load. the modeling of the system was made starting from a three-dimensional model, using the software ansys, version 10.0, that has as base the method of the finite elements, in which different rupture models were considered for the materials, besides contact elements in the interfaces of the materials. the finite elements, as well as the materials used were chosen in function of representativeness for the behaviors to be simulated, in thus was possible the consideration of important effects as plasticity and ortotropia for the materials. the results obtained from the proposed modeling were compared with the experimental results of shear tests in composite specimens with load applied until the rupture, and the error obtained, in this case, was 15%. the aim of this work is to serve as base for the modeling of structural systems, present in several areas of engineering, among them, mechanics and civil, where materials with different structural behaviors are used. the proposed modeling makes possible the global analysis of the model and locates aspects of interest as the concentration of stress, effect of difficult quantification in an experimental analysis.
