Sažetak
The research objective in this paper was determination of the influence of the reduced geometrical characteristics of castellated beams on the value of elastic critical moment of lateral-torsional buckling (Mcr) in relation to the plated beams with the same geometrical dimensions (same height, width and thickness of flange, and web thickness). Elastic critical moment for the lateral-torsional buckling has been calculated according to the expression given in Eurocode 3 (ENV 1993-1-1:1992, Annex F), and applying the finite element method with the linear buckling analysis. Analysis of the simply supported beams with various spans subjected to two types of the loading (uniform and concentrated) is performed.
