Analytical model for cellular beams made of hot rolled sections in case of fire
type: Dataset
description: This thesis has developed an analytical model for the prediction of the critical temperature of cellular beam made ​​based rolled in fire situation. These results will be based on the development of a new analytical model of isostatic cellular beam subjected to fire. To ensure the reliability of the developed model, the following steps were considered: The realization of large-scale tests in the laboratory, the development of a finite element model in the SAFIR software; Validation of finite element model in comparison tests laboratory, development of simplified analytical model, validation of the analytical method by a parametric study using the finite element model. The finite element model and the analytical model is able to reproduce with a satisfactory level of precision the complex behavior of cellular beams in case of fire
