Abstract This paper presents an investigation on the influence of structural imperfections ultimate load capacity steel welded beam-columns with class 4 cross-section under elevated temperatures. is done by considering different amplitudes for global and local (plate) imperfections, residual stresses distributions available in literature. To this purpose, a geometrically materially non-linear f...

There is no commonly accepted and reliable design method to determine the lateral–torsional buckling (LTB) resistance of steel trapezoidally corrugated web girders. Therefore, focus current paper on investigation this failure mode, detailed evaluation structural behavior determination accurate LTB resistance. An advanced finite element (FE) model developed validated using results laboratory tes...

The finite element model-based design of steel structures is getting increasing attention by designers, especially in the case buckling problems welded plated and static check interacting stability behaviour. FEM-based approach introduced standardised EN 1993–1-5 Annex C providing ability to calculate resistance based on direct geometrical material non-linear analysis using imperfections (GMNIA...

In this work, collapse of corroded pipeline under combined external pressure and tension is investigated through numerical method. Axially uniform corrosion with symmetric imperfections is firstly considered. After verifying with existing experimental results, the finite element model is used to study the effect of tension on collapse pressure. An extensive parametric study is carried out using...

Georges Perec's La Vie mode d'emploi ( Life: A User's Manual) was famously based on a number of meticulously crafted lists, including list errors that should be made in the writing each chapter. The engagement with imperfection novel is central way it balances structure and composition random exchangeable elements throughout his work plays significant role. In this article, I will move from to ...

We propose in this paper a method based, on the one hand, on possibility theory to calculate the similarity among the objects of any casebase, taking into account the imperfection and the heterogeneity of data, and based, on the other hand, on the geometric models like the linear and the circular unidimensional scaling and on the graphic models like the ultrametric trees in order to represent a...
