Two Stochastic Methods to Model Initial Geometrical Imperfections of Steel Frame Structures
BuildingsThe stochastic modeling of geometrically imperfect steel frame structures requires statistical inputs for imperfection parameters, often with specific mutual correlations. The stochastic input values of geometrical imperfections are derived from European

On the method of calculation of buckling and post-buckling behavior of laminated shells with small arbitrary imperfections [PDF]
Acta Scientiarum Polonorum. Architectura, 2021 In the present paper the variant of computational methods of stability and initial post-buckling behavior of isotropic shells was generalized with respect to laminated composite shells. Using methods of the asymptotic analysis of the Timoshenko–Mindlin

Post-Buckling Behaviour of Steel Structures with Different Types of Imperfections
Applied Sciences, 2022 In this paper, the stability of steel members with a complex initial geometrical imperfection pattern are analysed. This issue is extremely important in the case of slender structures, characterised by multiple close critical loads and modal interactions,

Numerical Homogenization of Single-Walled Corrugated Board with Imperfections
Applied Sciences, 2022 Numerical homogenization is an excellent tool for the quick simplification of complex structures with a model that is much simpler and, at the same time, accurately reflects the mechanical behavior of the original model.

Problems of lamella flanges in steel bridge construction [PDF]
Građevinski Materijali i Konstrukcije, 2016 As the plate elements of ordinary lamella flanges always exhibit unavoidable initial geometrical imperfections, a gap always occurs between them, into which the loaded lamella is pressed under load. Given the fact that the loading is many times repeated,
