This video demonstrates lateral torsional buckling of an aluminium alloy plate girder subjected to four point bending.
Learning Outcomes.
Viewers will gain an improved understanding of:
- Lateral torsional buckling
- The importance of providing adequate lateral and torsional restraint to beams
The plate girder is restrained in torsion at either end of the span. The video demonstrates how the strength of the beam rapidly decreases as the top, compression, flange buckles rotating sideways and downwards.
