Equivalent geometric imperfections for the LTB‐design of members with I‐sections
Steel Construction, Volume 15, Issue 4, Page 213-228, November 2022., 2022 Abstract For the stability assessment of members and structures according to EN 1993‐1‐1, the equivalent member method, the geometrical non‐linear calculation with equivalent geometrical imperfections or the GMNIA analysis with geometrical imperfections and residual stresses can be used alternatively.

Local Buckling of Compressed Cold‐Formed Lipped Channels via Buckling Mode Shapes
ce/papers, Volume 5, Issue 4, Page 178-185, September 2022., 2022 Abstract The effective width method is the most well‐known approach to determine the resistance of cold‐formed members using design formulas, accounting for the effect of local and distortional buckling. Local buckling is usually the most dominant failure mode of compressed C channels.

Torsional behaviour of thin‐walled members with regular perforation systems
ce/papers, Volume 4, Issue 2-4, Page 343-350, September 2021., 2021 Abstract Thin‐walled cold‐formed (TWCF) steel members that are frequently used in steel storage rack systems generally present a monosymmetric cross‐section. The adopted design approaches derive strictly from those developed for the more traditional bisymmetric solid web members, despite i) the presence in rack components of the eccentricity between ...

Bending torsion in Γ-shaped rigid and warping hinge joints
Magazine of Civil Engineering, 2020 This paper investigates the effect of bending torsion which is the cross-sectional warping of thin-walled rods at plane frame joints in the framework of the “semi-shear” theory of V.I. Slivker.

Nonlinear Buckling Analysis of Thin‐Walled Box Beams considering Shear Lag
Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020 In this work, a general geometric nonlinear model of straight thin‐walled box beams (STBBs) under combined eccentric and axial loads is established. In order to accurately reflect the behavior of STBB, the additional shear lag warping is added to enrich the displacement field.

Cold-formed steel joints with partial warping restraint
Magazine of Civil Engineering, 2021 The article investigates the influence of joints on the warping torsion of cold-formed steel bars. The modern warping torsion theory suggests cold-formed steel bars to be simply supported or fixed at the ends.
