ESTRUTURAS MISTAS (CONCRETO E AÇO): Estudo comparativo do projeto de um pavimento composto por lajes mistas “Steel Deck” e Lajes Maciças de concreto armado

Abstract

The need of constructions methods modernization has incorporated composite structures to edifications projects. Composite structures are those that are designed for two materials, concrete and steel profiles, resists jointly to internal forces. One of the applications of these structures is in buildings slabs, being known as composite slabs with profiled steel sheeting (Steel Deck). This slab is made with a profiled steel sheeting, which initially serves as a steel mold and supports the permanent actions and construction actions and, after hardened concrete, this mold isn’t removed and works as the tensile armor. In this sense, the objective of this is to conduct a comparative study of a commercial building pavement using concrete slab and composite slab (Steel Deck). For this was necessary a bibliographical research about the slab systems, and has been studied the calculating methodology of the two systems and developed a case study in order cooperate which slab type will serve better in a building study.
