Introduction to Structural Mechanics

This lecture introduces the fundamental concepts of structural mechanics, covering topics such as the nature of static forces, stress, strain, and structural elements like bars, cables, trusses, and beams. It also delves into the limits of elastic deformation, inelastic deformation, and elastic buckling. The course provides a foundation for understanding the deformation and internal loads of structures through force/moment balance, constitutive relations, and compatibility conditions. Additionally, it places these introductory concepts within the broader context of advanced topics in solid and structural mechanics.
