The increase in the use of mixed structures in civil engineering works in particularly of steel and concrete because of its considerable gain in its properties mechanical properties when materials work together in relation to common structures, contribute to a great contribution in the economy and in the practice of the construction. Focusing on steel and concrete beams, there is a particular form that distinguishes it from other types of beams, such as the partial interaction between components, where sliding occurs steel and concrete elements when connected by shear. In addition to the partial interaction between materials, the other consideration is the correct dimensioning of the mixed connection in the supports of the mixed beam element, therefore it is necessary to study each element that constitutes it, hence the requirement of complex calculations. The strength of all components, rigidity and rotatability will be the basic analyzes to be carried out. The performance-based project tends to do behavior analysis of the structure of real form, which takes to carry out a thorough and complete work. Hence the incorporation of the Finite Element Method. The purpose of this dissertation is to develop, implement and verify numerical models based on the method of the Elements Finites, considering not only the physical and geometric non-linearity for the advanced analysis of beams, but also the effects of the partial and semi-continuity interaction of the beam in the of the elements. The implementation of the model will be based on the SOUSA model Jr. (2013). The results obtained after the analysis will allow to evaluate and to compare with analysis that use the calculation of efforts in elastic regime and its validation. Because of this, it is necessary to readjust the non-linear models that will be developed through comparisons with other numerical results as well as existent in the literature. This way you can check the accuracy and reliability of the proposed element model.
