LTB in the Eurocodes – Back to the Future
In Part 1, David Brown of the SCI looked at comparisons between lateral torsional buckling in BS 449 and BS 5950. In Part 2, the comparison is extended to the …
A brief history of LTB
David Brown of the SCI reviews the (relatively) recent history of lateral torsional buckling of beams. Part 1 includes a reminder of the underlying structural …
AD 391: Lateral Torsional Buckling of rectangular plates in accordance with BS EN 1993-1-1
BS EN 1993-1-1 does not explicitly cover LTB of rectangular plates. This AD note provides guidance for calculating the design buckling resistance moment that …
Design of steel portal frame buildings to Eurocode 3
Dr Richard Henderson examines SCI’s publication P399 on portal frame design. In order to retain the accurate formatting of the equations in this technical …
Simplified assessment methods for LTB
David Brown of the SCI considers the simplified assessment method for lateral-torsional buckling given in EC3, and finds a useful application in elastic portal …
Lateral torsional buckling and slenderness
The expression for slenderness used in the lateral torsional buckling checks given in BSEN1993-1-1:2005 is different to that given in BS5950-1:2000. Mary …
