- Fire resistance of composite slabs with steel deck and insulation materialPublication . Lucca, Gabriel Turczyn De; Piloto, P.A.G.; Balsa, Carlos; Kimura, EricaA composite slab is defined as a steel profile with concrete on top, and when the concrete reaches its expected strength, the two elements start to work as one through indentations and geometry. This technology has been used since the 1980s in Europe, mainly in the United Kingdom; however, it was only in 1983 that the first technical standard for the calculation of this type of structure was released. These standards were and still are based on experimental studies by various authors. However, since the cost of conducting these tests is very high, the technique of using finite elements and numerical simulation has been expanding in recent years as an alternative to replace or validate these laboratory studies, proving to be highly effective when properties are correctly inserted. This dissertation presents the numerical study conducted to validate the temperature field of a laboratory experiment, using the ANSYS software. It also validates the maximum load-bearing capacity at ambient temperature compared to analytical calculation and presents the calculation of the maximum load-bearing capacity when the temperature field is applied for up to 120 minutes. The study proved capable of representing temperature fields and validating the loadbearing capacity of the slab in the software, demonstrating that such studies when the correct properties are applied, can support experimental studies.
