The Stability of Frames provides a vivid picture of phenomena affecting the stability of plane, rigid-jointed, triangulated and non-triangulated frames. This book discusses the energy methods that are of prime importance in dealing with the stability of isolated members and of plate elements within members. Organized into five chapters, this book begins with an overview of the essential features of stability in elastic and elastic-plastic structures by reference to single members bending about one axis. This text then examines the stability functions for prismatic elastic members. Other chapters consider the elastic stability of triangulated frames and with non-triangulated frames. This book discusses as well the principles of structural analysis that are the same for all frames, whether or not axial loads in members are sufficient to affect their stiffness. The final chapter deals with the behavior of both triangulated and non-triangulated frames beyond the elastic limit. This book is a valuable resource for engineers.
