| Resumo: | This paper presents finite element thermal models to evaluate the thermal behavior of composite slabs with steel deck, submitted to standard fire exposure. Composite steel/concrete slabs are a mix of a reinforced concrete layer with a profiled steel deck reinforced by steel bars between its ribs. The resulting transient and non-linear thermal problems are solved numerically with threedimensional multi-domain finite element models. The models were developed for normal weight concrete and lightweight concrete, and for different steel deck geometries (trapezoidal and re-entrant). The results of the numerical simulations are used to present a new calculation method to determinate the temperatures on the steel deck components and on the rebars and, consequently, to determine the bending resistance of composite slabs under fire conditions. |
