The objective of the paper is to analyse the influence of initial imperfections on the load-
carrying capacity of a single storey steel plane frame comprised of two columns loaded in …

Transversely loaded beam grillages are quite often used in industrial construction. In order
to produce a safe design of such structures, it is necessary to account for the lateral torsional …

The paper deals with the load carrying capacity probabilistic variance-based sensitivity
analysis of thin-walled box-section girders subjected to pure bending. The lower-and upper …

The paper deals with local buckling of the compressed flanges of cold-formed thin-walled
channel beams subjected to pure bending or axially compressed columns. Arbitrarily …

Multicellular thin-walled tubes are widely used due to their lightweight, economical design,
and superior shear and torsional performance. Their design is sometimes governed by the …

The present paper deals with an influence of the distortional-lateral buckling mode on the
interactive buckling of thin-walled short channels with imperfections subjected to the …

The paper presents the numerical study of the stability of steel beams for various
slenderness ratios of the web and various types of stiffening ribs. FEM analyses employing …

Abstract Design and optimization, as well as real time control, of flexure mechanisms require
efficient but accurate models. The flexures can be modelled using beam elements and the …

The results of studies upon the suitable numerical model, within the method of finite
elements have been presented herein, in order to enable the rational computation of the …

The first order variation of critical loads of thin-walled columns with bisymmetric open cross-
section due to some variations of the stiffness and location of bracing elements is derived …
