Abstract
In this paper, one provides a robust modelling for the screw-attachment of large light partition wall between plasterboard (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 fit the 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 theMaximum Entropy Principle under the constraints defined by the available information. The identification of unknown parameters of the probability model is performed using the experimental data which lead us to an optimization problem which has to be solved. Finally, the numerical results are presented and validated with experiments. Keywords: screw attachment, plasterboard, probabilistic model, experimental identification.
