Comparison of Buckling Resistance of I-shaped cross-sections

by two software packages and compares the buckling resistance to Winter curves in Eurocodes. Highlights: Recommendation for a choice of imperfection amplitudes for local buckling, global buckling, and a combined local and global buckling is provided In terms of local buckling, the imperfection amplitude of d /200 showed a good agreement with the EN 1993-1-5 “Winter curve” for plate buckling.

Lateral-torsional buckling of a beam with transverse stiffeners

Member - Lateral-torsional buckling The comparison of results is in the table below. F cr is the critical buckling load determined by LBA. IDEA Member provides slightly lower critical buckling load and slightly higher lateral-torsional buckling strength.

Comparison of the Buckling Resistance of SHS and RHS Profiles

This verification study is focused on local and global buckling simulated with advanced analyses. Highlights: An overview of imperfections for global and local buckling in EN 1993-1-1 and EN 1993-1-5 is given and various options are compared. Conclusions: Linear buckling analysis: IDEA StatiCa Member provides very similar results to Abaqus with a difference below 5%.

Geometrically and materially nonlinear analysis with imperfections (GMNIA) of columns in compression

Buckling resistance in direction of both principal axes is verified. The results for strong axis buckling are summarized in the table below. Weak axis buckling The results for weak axis buckling are summarized in the table below.

Web in transverse compression

Cl. EN 1993-1-5, Cl. 6 In AISC 360-22, there are clauses for web local yielding in J.10.2, web local crippling in J.10.3, and web compression buckling Web sideways buckling is assumed to be structurally restrained and is not investigated here. Buckling factor 3 from LBA is a suitable limit.

Geometrically and materially nonlinear analysis with imperfections (GMNIA) of beams in bending

The A, B, and C approach uses the initial imperfection for the weak axis buckling multiplied by a factor of k = 0.5; as specified in EN 1993-1-1 Clause The initial imperfection according to approach D is determined directly for lateral torsional buckling. Lateral torsional buckling design imperfections for use in non-linear FEA.
