Abstract EN
The uncertainty is a typical feature of each human activity since the greatest part of the information is always affected by a sure level of scattering.
Different methodologies which deal with the uncertainty of the real problems exist.
The principal aim of this paper is to present an innovative hybrid approach which combines fuzzy and stochastic theories in facing the structural analysis of a tuned mass damper subject to a dynamic random load, modelled by a modulated filtered white noise.
In this work the parameters involved in the structural analysis will be considered uncertain and supposed fuzzy sets to take into account the effects of lexical and informal uncertainties which cannot be studied in a probabilistic way.
The system analysis is conducted by means of α-level optimization technique.
Successively, a numerical example is presented to show the effectiveness of the proposed procedure.
Moreover, a sensitivity analysis is performed to expose the variation of the structural response membership function considering different input values.
Finally, a comparison between the response nominal value and the fuzzificated one is proposed to obtain a structural amplification factor.
