ABSTRACT<br />
KIRCHHOF, L.D. (2004). A contribution to the study of simply-supported composite steelconcrete<br />
beams in ambient temperature and in fire situations. São Carlos, 2004. 143p.<br />
Dissertação (Mestrado) – Escola de Engenharia de São Carlos, Universidade de São Paulo.<br />
Composite steel-concrete beam have been commonly considered in steel-framed building<br />
used in civil engineering, not only in Brazil but also in the worldwide context. The<br />
efficiency of this structural element is directly related with the type of interaction between<br />
steel beam and concrete slab, which is assured using metallic elements called shear<br />
connectors, with the objective to transfer longitudinal shear forces from concrete slab to<br />
steel beam, in the interface, and avoid the vertical separation between concrete slab and<br />
steel beam (uplift).In this sense, the aim of the present work is to carry out a bibliographical<br />
review about composite steel-concrete beam, as well as propose a three-dimensional nonlinear<br />
procedure for modeling only full shear connection in composite beam. The threedimensional<br />
numerical models constructed must be capable of predicting de response of<br />
composite beam, in ambient temperature an also in elevated temperatures (fire conditions).<br />
The computer program ABAQUS® 6.3-1, based on Finite Element Method, was used to<br />
analyze the numerical modeling. The accuracy of the three-dimensional numerical models<br />
are demonstrated by analyses of the results obtained with the models which are compared<br />
with the experimental results, obtained and presented by others researches.<br />
