EnglishIn the framework of stochastic analysis, the extreme response value of a structural systemis completely described by its CDF. However, the CDF does not represent a direct designprovision. A more meaningful parameter is the response level which has a specified probability,p, of not being exceeded during a specified time interval. This quantity, which isbasically the inverse of the CDF, is referred to as a fractile of order p of the structuralresponse. This study presents an analytical procedure for evaluating the lower boundand upper bound of the fractile of order p of the response of linear structures, with uncertainstiffness properties modeled as interval variables subjected to stationary stochastic excitations.The accuracy of the proposed approach is demonstrated by numerical results concerninga wind-excited truss structure with uncertain Young’s moduli.
