Conventional and advanced bending strength analysis of common and castellated, homogeneous and hybrid I-beams

An appropriate investigation has been performed in order to estimate the bending strength safety of steel I-beams typical in traditional and up-to-date computational analyses. The bending strengths of the conventional analysis have been set in general form for the beam parameters of the span/depth ratios usually observed. Mutual strength relationships between common and castellated, homogeneous and hybrid I-beams, reflect the anticipated regularities. Use of the advanced analysis, founded on the non-linear FEM approach, required the solution of adequate practical examples. In view of the research class, certain completion of the typical non-linear procedure was needed.
