20.500.12556/RUL-32131 Buckling of an axially restrained steel column under fire loading Analytical procedure, based on the linearized stability analysis, is presented for the determination of the buckling load and the buckling temperature of a straight, geometrically perfect, axially loaded steel column subjected to an increasing temperature simulating fire conditions. The nonlinear kinematical equations and the nonlinearity of material are considered. The stress strain relation for steel at the elevated temperature and the rules for reduction of material parameters due to increased temperature are taken from European standard EC 3. Theoretical findings are applied in the parametric analysis of a series of Euler's columns subjected to two parametric fires. It is found how the slenderness of the column, the material nonlinearity, the temperature dependence of material parameters, and the stiffness of restraints at supports effect the critical temperature. While these parameters have major influence on the critical temperature, they have no effect on the shape of the buckling mode. steel columns inelastic buckling critical temperature fire analysis high temperatures Reissner beam jekleni ukloni nelinearni uklon kritična temperatura požarna analiza povišane temperature Reissnerjev nosilec nosilci true false false World Scientific Publishing Angleški jezik Angleški jezik Neznano 2015-07-10 10:12:16 2015-07-10 10:12:17 2022-11-21 15:19:46 0000-00-00 00:00:00 2011 0 0 Str. 451-472 št. 3 Letn. 11 2011 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 624.07 0219-4554 10.1142/SO219455411004245 5405537 517367321 Hozjan_et_al_Int_J_Struct_Stability_Dynamics_Vol_11_2011_451%2D472.pdf Hozjan_et_al_Int_J_Struct_Stability_Dynamics_Vol_11_2011_451%2D472.pdf 1 17D107268D9913DE421C9004A90E0F59 c923372dbc96ce0645c613e05721091e50f675aa172b4b891c43e160c5e57cdd 1074eb2b-a1ae-11eb-a523-00155dcfd717 20.500.12556/rul/f629a3fc-0e23-45e5-87be-1325bb272695 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=85642 Fakulteta za gradbeništvo in geodezijo 0 0 0
