Mejna stanja in kombinacije obtežbHolický, Milan ...Novi evropski standard Eurocode EN 1990 - Osnove projektiranja obravnava med drugim tudi pravila za kombinacijo vplivov obtežb, ki so v tem prispevku ilustrirani s primeri analize enostavnih ... konstrukcij. Vrednosti parcialnih faktorjev obtežb in redukcijskih faktorjev, ki so uporabljeni pri preverjanju mejnih stanj nosilnosti vključujoč statično ravnotežje ter pri preverjanju mejnega stanja uporabnosti, so določene v skladu z napotki iz standarda EN 1990. Vplivi obtežb, določeni po različnih variantah kombinacij obtežb so predstavljeni kot ovojnice upogibnih momentov in v primeru statičnega ravnotežja tudi kot strižne sile. Primerjava dobljenih vplivov obtežb nakazuje dejstvo, da lahko različne variante kombinacije obtežb privedejo do precejšnjih razlik v velikosti vplivov, tudi do 18%. Kaže, da so potrebne dodatne raziskave glede odločitve o primernih variantah kombinacij obtežb, ki naj upoštevajo ekonomske in komercialne vidike, kot tudi stopnjo težavnosti projektnih metod in rezultati katerih naj se odražajo v primernem nacionalnem dodatku k standardu EN 1990.Type of material - conference contributionPublish date - 2005Language - slovenianCOBISS.SI-ID - 27703813
