Selection of the initial geometrical imperfection in nonlinear FE analysis of cold-formed steel rack columns

open access: yes, 2011
This paper presents three methodologies to predict the load carrying capacity of cold formed steel rack columns via nonlinear finite element analysis (FEA). The column lengths are chosen in the range where the main failure is due to distortional buckling.

Collapse behaviour of steel columns in fire. [PDF]

open access: yes, 1988
The three years' work undertaken in this project is a purely numerical analysis of the inelastic behaviour of steel columns in fire. This is made up of three main parts, each devoted to the development and use of a numerical technique to study the ...

Axial force and bending stiffness

open access: yesMATEC Web of Conferences, 2017
In the solution of effects of axial force on the bending stiffness, geometrical nonlinear analysis must be used. Tensile axial force generates an increase of the bending stiffness. In case of low bending stiffness (e.g.

Numerical Study of Geometrical Imperfection Response on Composite Cylinders under Axial Loading

open access: yes
Buckling behaviors of geometrically imperfect glass fiber reinforced plastic cylinders under axial compression loading are investigated. The geometrical imperfections have been assigned to the cylinder by subdividing cylinder in equivalent parts and ...

Increasing the Bucking Capacity with Modal Geometric “Imperfections”

open access: yesce/papers
Abstract A recent design paradigm, named modal nudging, exploit geometric “imperfections” with negligible self‐weight change to nudge the baseline structure onto equilibrium paths of greater load‐carrying capacity. Indeed, not all imperfections are detrimental in buckling problems.

Geometric imperfection measurements on cold-formed steel channels: An approach using 3D non-contact laser scanner

open access: yes, 2017
A 3D non-contact laser scanning method to quantify the deviations in cold-formed steel (CFS) channel sections (plain and lipped) is presented. The methodologies to segregate the different categories of imperfections from the deviations in the geometry of

Instability load evaluation of shallow imperfection-sensitive structures by form and interaction parameters

open access: yes, 2017
In terms of the interaction between buckling and snap-through for shallow structures affected by geometrical imperfections results have shown that, after the nonlinear bifurcation, load reductions occurs accompanied with a predictable tendency.
