Computational Nonlinear Thermomechanical Model of Large Light Partition Walls Based on Experimental Analysis and Probabilistic Models

This paper is devoted to the construction of a computational nonlinear thermomechanical model of large light partition walls made up of cardboard-plasterboard-cardboard (CPC) plates screwed to a metallic frame, and is submitted to mechanical and thermal loadings induced by fire. The computational model, based on experimental analyzes and a probabilistic modeling, is developed for the prediction of a large light partition wall for (1) its linear thermal behavior, (2) its nonlinear mechanical behavior and (3) its nonlinear thermomechanical behavior.
