Abstract

This contribution presents an approach for performing fuzzy structural analysis of linear structures subject to static loading where uncertainties are present in both material properties and loadings. The responses of interest are displacements of the structure. The proposed approach is based on a non-linear approximation of these responses. This non-linear approximation is constructed by taking into account the linearity of the displacements with respect to loading and by introducing intervening variables. In this manner, high quality approximations of the structural responses are obtained allowing to determine membership functions performing a single structural analysis.
