20.500.12556/RUL-124731 Stability behaviour of stiffened curved plates subjected to pure compression This paper investigates the stability behaviour and load carrying capacity of longitudinally stiffened, transversally curved steel plates under compressive stresses. The behaviour of stiffened, curved plates is a complex problem, especially due to the interaction of curvature, relative stiffness of the stiffeners and initial imperfections. A comprehensive parametric study is presented to investigate the effects of curvature, plate slenderness, size and shape of stiffeners on the ultimate resistance of stiffened curved plates. The aim of the study is to explain the behaviour of such structures and to demonstrate the benefits that can be obtained from bridge decks with curved plates. From the results some important conclusions are drawn regarding the structural behaviour and the positive effects of curvature on the cross-sectional resistance. A study on the influence of geometric imperfections on the load-bearing capacity is presented, which is based on the modification of nodal coordinates by means of sine-shape functions. true true true Angleški jezik Ni določen Znanstveno delo 2021-02-13 00:31:10 2021-02-13 00:31:12 2022-09-04 04:01:08 0000-00-00 00:00:00 2021 0 0 Str. 1-17 št. 107313 Letn. 159 feb. 2021 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 2020-06-22 2020-11-15 2020-12-04 2022-11-16 624.07 0263-8231 10.1016/j.tws.2020.107313 42017283 26529536 https://doi.org/10.1016/j.tws.2020.107313 1 4ac2d2f3-c2c7-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=143595 RAZ_Piculin_Sara_2021.pdf RAZ_Piculin_Sara_2021.pdf 1 8A1AAEBDC223E95AEE047DBCA98C3E54 34fb1cd291af94c639225628d3d56d69a7976a35f5565ad6ad39f64b25253492 a95ac57e-df12-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=144930 Fakulteta za gradbeništvo in geodezijo 0 0 0
