The buckling analysis of a cold-formed steel C-sectional column resting on an elastic foundation

MATEC Web of Conferences, 2018
The paper is focused on stability analysis of different models of steel cold-formed C-section column. The analysed element may be applied as a primary load-bearing member in steel trusses or silo columns. The column can be used as a support for a wall of

OPTIMIZATION AND POST-BUCKLING ANALYSIS OF A LONG SHAFT ROTOR SYSTEM WITH PINNED-STABILIZED SUPPORTED AT ARBITRARY POSITION

Jixie qiangdu, 2018
A nonlinear model of a pinned-free long shaft rotor system with a stabilized support at arbitrary position is established by employing the generalized Hamilton principle.

An Assessment of the Eurocode 3 Simplified Formulas for Distortional Buckling of Cold-Formed Steel Lipped Channels

Applied Sciences
This paper concerns the Eurocode 3 Part 1-3 (EN 1993-1-3) methods for calculating the distortional buckling (bifurcation) load of cold-formed steel-lipped channels subjected to axial force, major and minor axis bending.

Free-Vibration and Buckling Analyses of Beams using Kriging-Based Timoshenko Beam Elements with the Discrete Shear Gap Technique

Civil Engineering Dimension
A family of locking-free Kriging-based Timoshenko beam elements with a new implementation of the discrete shear gap technique was recently developed (referred to as K-beam-DSG1 elements). Performance of the K-beam-DSG1 elements has been shown to be very

Buckling of a Nonlinearly Elastic Column: Variational Principles, Bifurcation and Asymptotics

Rocky Mountain Journal of Mathematics, 1995
We study the equilibrium states of an elastic column subject to an end thrust. The column is modeled as an inextensible rod with a nonlinear moment-curvature equation. We bring various mathematical theories to bear on this problem; the calculus of variations, bifurcation theory, phase plane analysis, and singular perturbation theory for ordinary ...

Least-squares Smoothed Shape Functions for Constructing Field-Consistent Timoshenko Beam Elements

Civil Engineering Dimension
This paper presents an approach for constructing field-consistent Timoshenko beam elements using least-squares smoothed (LSS) shape functions. The variational basis for shear strain redistribution is thoroughly explained, leading to the derivation of ...
