WebThe lateral buckling of glued laminated beams is governed by the parameter Ld/b 2, not by d/b as is assumed by many building codes. Simple equations are derived for the critical buckling stress and the allowable design stress for rectangular timber beams with various support and load conditions. The concept of short, intermediate, and long ...

LATERAL TORSIONAL BUCKLING AND ITS CAUSES

WebIn an unrestrained beam, the compression flanges of the main beams tend to buckle horizontally, causing the beam to twist – so called lateral torsional buckling. This can be resisted by bracing that provides either direct lateral restraint to the compression flanges or torsional restraint to the whole beam. WebSimilar to the behavior of a column ( Art. 3.41 ), a beam, although the compressive stresses may be well within the elastic range, can undergo lateral buckling failure.
