RESUMO

The pre-fabricated elements has been occupying its space more and more in the several buildings of Civil Engineering. The trussed slabs appeared as a variation of these elements. This work tried to meet the maximum information that facilitate to characterize this element in national level, as well as he is treated at European countries, like France. Through the rehearsal of simple bending in ten models, four in rectangular section and six in section T, tried to represent in a satisfactory way the real manner of its use in buildings, looking for the characterization of the trussed beam. Measures were made of the vertical arrows, deformations in the top bars and diagonals and the characterization of the development and propagation of the cracks. The rehearsals showed that the diagonals don t work hard in the action of the shear efforts, the cracks appear for the first applied loads and there is need of application of the counter-arrows in the concrete stage of the precast slab
