The elastic load-carrying capacity and buckling trajectory of steel columns under compression with open and hollow cross-sections, whose axis is curved by spatial random fields, are studied in the article. As a result of the spatial curvature of the

A methodology for thin-walled frame analysis using displacement modes of beams at joint interfaces has recently been proposed. This paper introduces an implementation that uses a specific advanced beam element based on semi-analytical beam mode solut

The accuracy of the interaction methods for combined flexural and lateral torsional buckling are investigated using statistical data, which has become available after the introduction of Eurocode EN1993-1-1:2005. The freely available statistical data

Publikováno v: Jönsson, J & Stan, T-C 2017, ' European column buckling curves and finite element modelling including high strength steels ', Journal of Constructional Steel Research, vol. 128, pp. 136-151 . https://doi.org/10.1016/j.jcsr.2016.08.013

Eurocode allows for finite element modelling of plated steel structures, however the information in the code on how to perform the analysis or what assumptions to make is quite sparse. The present paper investigates the deterministic modelling of fle
