Resumo(s)
This work aims to improve the estimation of the temperatures on the steel deck under fire. An accurate estimation of these temperatures is crucial to determine the load-bearing capacity (R) of the slab. An analytical method, alternative to the simplified method provided by Eurocode 4, that enables temperature estimation on the steel deck components (web, lower and upper flange), is derived from the numerical results, obtained with a three-dimensional computational model. This new proposal considers the effect of the concrete thickness ℎ1, enables to obtain unbiased temperatures and, contrary to the Eurocode 4 proposal, fits very well the numerical results.
