Lecture
This lecture delves into the detailed explanation of the stability verification of frame columns, covering cases of element instability, bending prevention, and interaction verification formulas according to SIA 263. It explores the Eurocode 3 stability formulas, the principles related to SIA 263, and the simplified EN1993-1-1 verification formula. The lecture also discusses the effects of bending-torsion interaction, flexible frame elements, and the considerations for buckling and spillage in metal structures.
