Constitutive equation for the screw-attachment in plasterboards. Probabilistic model and its experimental identification
Abstract : One provides a robust modelling for the screw-attachment of large light partition wall between plasterboards (CPC) plate and metallic frame. The analysis of shear behaviour of this attachment under mechanic loads has been carried out by using an experimental approach taking into account the complexity of the mechanical systems. A deterministic model is then proposed to
t the experimental results. A mean model is identi
ed using the experiments. Since there is variability in the experimental results and since the mean model corresponds to a rough approximation, there are uncertainties in the mean model which are taken into account with a parameter probabilistic approach. The probabilistic approach of uncertain parameters is constructed using the Maximum Entropy Principe under the constraints de
ned by the available information. The identi
cation of the unknown parameters of the probability model is performed using the experimental data which lead us to an optimization problem which is solved. Finally, the numerical results are presented and validated with experiments.
