Virtual Work and Energy Methods

  • J. D. Todd


Much of the work covered in the last three chapters has been devoted to the behaviour of an individual member when subjected to various types of loading. We shall now investigate framed structures made up of a number of individual members that may either be pinned together at their ends or rigidly jointed. A number of ideas and methods will be presented that will enable the deflections of points on such structures to be found; or the forces may be found for the members in statically indeterminate cases. The chapter also provides an introduction to a later chapter on stiffness and flexibility methods, which are fundamental to a modern approach in structural analysis and can in fact be applied to all types of structures, including framed structures, plates, and shells.
