20.500.12556/RUL-127238 Ultimate resistance of longitudinally stiffened curved plates subjected to pure compression [No.] 106616 Design guidelines are proposed for the calculation of the ultimate resistance of longitudinally stiffened, transversally curved plates subjected to uniform compression. They represent internal plated members of box-girders. The proposed method is in accordance with the Eurocode formalism and follows the effective width concept from EN 1993-1-5. The latter strongly underestimates the resistance of stiffened, curved plates. Therefore, the new method extends the scope of the current European standards from flat to curved plates. A general form of the buckling coefficient is derived for orthotropic shell buckling, which is consistent with the solution for orthotropic buckling of plates according to Annex A, EN 1993-1-5. The method presented combines the new equation with the existing design proposals for unstiffened curved panels from the literature and the current design rules for flat plated structures according to EN 1993-1-5. The method is compared with numerical results on simply supported, cylindrically curved panels stiffened with trapezoidal longitudinal stiffeners, where the longitudinal edges are unconstrained and loaded edges are constrained, and a good correlation is achieved. civil engineering structures stiffened curved plates box-girder bridges design resistance uniform compression effective width concept gradbene konstrukcije ojačane ukrivljene pločevine mostovi s škatlastim nosilcem projektna nosilnost enakomerni tlak koncept sodelujoče širine true true true Angleški jezik Slovenski jezik Znanstveno delo 2021-05-27 10:02:03 2021-05-27 10:02:07 2022-09-06 03:50:17 0000-00-00 00:00:00 2021 0 0 Str. 1-19 Letn. 181 jun. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2020-12-06 2021-02-26 2021-03-10 2023-02-26 624.014.2:624.042.7 0143-974X 10.1016/j.jcsr.2021.106616 55159299 RAZ_Piculin_Sara_2021.pdf RAZ_Piculin_Sara_2021.pdf 1 827D24A4C6969094312B0241C259B895 63c54bf81a96af8276691873bb6a0134f6ee4aa05b84d6897e03686b38d5cf33 e16e80c1-bec2-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=143536 Fakulteta za gradbeništvo in geodezijo 0 0 0
