The proposed technique can be construed as a two-stage approach. First, relying on statistical linearization and utilizing a dimension reduction approach the nonlinear n-degree-of-freedom system is decoupled and cast into (n) effective single-degree-of-freedom (SDOF) linear time-variant (LTV) oscillators. Second, utilizing the effective SDOF LTV oscillator time-varying stiffness and damping elements in conjunction with a stochastic averaging treatment of the problem, the MDOF system survival probability and first- passage PDF are determined. Overall, the developed technique appears to be efficient and versatile since it can handle readily, at a low computational cost, a wide range of nonlinear/hysteretic behaviors as well as various stochastic excitation forms, even of the fully non- stationary in time and frequency kind. A 3-DOF system exhibiting hysteresis following the Bouc-Wen model is included in the numerical examples section. Comparisons with pertinent Monte Carlo simulations demonstrate the accuracy of the technique"},{"@xml:lang":"sl","#text":"Naravne sile, ki vzbujajo dinamične sisteme, kot so npr. veter, valovi in seizmične obremenitve, so pogosto evolucijske narave. V takšnih pogojih se močno spreminja tako intenzivnost vzbujanj kakor tudi njihova frekvenčna vsebina. Ta razred strukturnih obremenitev je zato treba popisovati z nestacionarnimi stohastičnimi procesi. Močno vzbujani konstrukcijski sistemi lahko izkazujejo tudi značilno nelinearno vedenje s histerezami. Za skupnost, ki se ukvarja z dinamiko konstrukcij, je zato zelo pomemben razvoj tehnik za določanje odziva in vrednotenje zanesljivosti nelinearnih/histereznih sistemov, izpostavljenih evolucijskim stohastičnim vzbujanjem"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-Z7YN9FYG","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-Z7YN9FYG"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-Z7YN9FYG/69bd0864-e33a-4dbe-8166-6077d99621f4/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-Z7YN9FYG/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-Z7YN9FYG"}}}}
