Abstract
Considers the problem of structures' sensitivities to prescribed displ acements uncertainties through the use of fuzzy numbers. Important pro perties of fuzzy subsets have been studied and used to model uncertain ties, and to solve the fuzzy linear system resulting from taking into account the uncertainties on prescribed displacements. Develops a comp uter program to allow comparisons between several structural designs c hecking common specifications. Demonstrates the effectiveness of the p resent method for a cantilever structure modelled in the case of a sta tic finite element analysis.
