Resumen/Abstract

This study aims to analyse the importance of gypsum plasterboard cardboard for fire resistance. A new hypothesis considering the failure based on the cardboard degradation is defined. This hypothesis comes from the thermal analysis of gypsum and cardboard performed in the simultaneous thermal analysis apparatus. Simultaneous thermal analysis results also allow defining the dehydration process of the gypsum. A numerical model that considers gypsum dehydration and the failure hypothesis has been developed by using Fire Dynamic Simulator. This numerical model is validated against 6 fire resistance tests. Results show that we can appropriately tune the numerical model (for predicting time to failure) based on the thermal properties of cardboard.
