A. Cherki et al., ON EVALUATING STRUCTURES SENSITIVITIES TO PRESCRIBED DISPLACEMENT UNCERTAINTIES USING FUZZY NUMBERS, Engineering computations, 14(5), 1997, pp. 529
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.
