Approximate fuzzy analysis of linear structural systems applying intervening variables

摘要

This contribution presents an approach for performing approximate fuzzy structural analysis of linear static systems. The proposed approach is based on an approximate representation of the structural displacement (which is constructed using intervening variables) and is capable of dealing with uncertainty present in both structural parameters and loading. The most salient features of the proposed approach are its capability of capturing the nonlinearity of the structural response with respect to uncertain parameters and its numerical efficiency.
