Estruturas mistas de aço e concreto: dimensionamento de laje em Steel Deck de um pavimento

Abstract

The collaboration between a steel profile and concrete results in a steel-concrete composite element, such as a composite beam or composite slab. Currently, the majority of buildings in Brazil could already be built using a mixed system, but there is still a significant concern in the civil engineering sector of adopting new techniques. With this in mind, this paper first presents a literature review in which the main concepts of steel-concrete composite structures are discussed, such as composite beams, shear connectors and steel deck slabs. Next, a case study was carried out in which a structure of steel deck slabs and composite beams was designed in a pre-existing metal building. All the necessary verifications were calculated in accordance with current standards regulations. Finally, using REVIT software, the BIM modeling of the mixed structure already designed was carried out.
