Stability of Structures: Principles and Applications

Chai Hong Yoo

The subject of this book is the stability of structures subjected to external loading that induces compressive stresses in the body of the structures. The structural elements examined are beams, columns, beam-columns, frames, rectangular plates, circular plates, cylindrical shells, and general shells. Emphasis is on understanding the behavior of structures in terms of load-displacement characteristics; on the formulation of the governing equations; and on the calculation of the critical load. Buckling is essentially flexural behavior. Therefore, it is imperative to examine the condition of equilibrium in a flexurally deformed configuration (adjacent equilibrium position). The governing stability equations are derived by both the equilibrium method and the energy method based on the calculus of variations invoking the Trefftz criterion.
