RESUMO

Widely used in civil engineering frameworks, steel-concrete composite beams appear as consequence of the use of steel beams with concrete slab, providing better management of each constituent material properties. To act as a composite element, it is necessary that the slab and the beam work together, aspect obtained by using metallic elements called shear connectors, that restrict the longitudinal slipping and the uplifting between steel beam and concrete slab. In this sense, this work presents three-dimensional numerical models of steel-concrete composite beams in order to simulate its structural behavior with emphasis, in particular, at the interface between steel beam and concrete slab. The numerical models are constituted of simply supported composite beams with plain faces slab and stud bolt shear connectors. The simulations had been carried out by means of the code ANSYS version 8.0, based on finite elements method. The results had been compared with experimental values, extracted of works presented by others researchers
