A new proposal for estimating the temperatures on the steel deck components of composite slabs under fire
| Resumo: | This study aims to improve the estimation of the temperatures on the steel deck of a composite slab under fire. An accurate estimation of these temperatures is crucial to determine the loadbearing capacity (R) of the slab. A new proposal, 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 and includes the fire rating and, contrary to the Eurocode 4 proposal, fits very well the numerical results. |
