Thermo-mechanical modeling of plasterboard- lined partition submitted to fire load

Abstract : An important problem is the development of a thermo-mechanical model of plasterboard lined partition submitted to fire load. A fundamental key to solve such a problem is the development and the experimental validation of a deterministic and a probabilistic thermo-mechanical model of cardboard-plaster-cardboard (CPC) submitted to fire load. The proposed model takes into account system parameter uncertainties and model uncertainties. The first part concerns the constitution of an experimental thermo-mechanical data base for a CPC multilayer and for its components.The second one is the development of an homogenization thermomechanical mean model for the CPC multilayer. This mean model is adapted to a temperature range in which plaster or cardboard may be damaged. The third part is devoted to the implementation of the probabilistic model. In the last part, we present the results of numerical simulations which are compared to the experimental data.
