This lecture covers the concept of buckling in metal structures, focusing on the influence of residual stress imperfections and elastic limits. It discusses the behavior of materials under different conditions, such as linear elastic and distorted states. The instructor explains the determination of buckling resistance through laboratory tests and provides examples of applications using rolled or welded hollow profiles. Additionally, the lecture addresses the factors affecting buckling curves and lengths, including support conditions and steel grades. Practical examples of post bases are presented to illustrate buckling around different axes.
