This course covers the fundamental principles of structural instability and buckling, focusing on rings, curved bars, and arches. It provides an in-depth understanding of the derivation of the governing differential equation for the deflection curve of a thin bar with a circular center line. The course also explores the concept of buckling under a uniformly distributed load and how to calculate the critical load of two hinge and fixed-fixed circular arches. It further delves into the difference between slender and short columns, introducing the double modulus theory and the tangent modulus theory. The course concludes with an illustrative example of inelastic buckling in columns, providing practical application of the theories discussed.
