ABSTRACT
In Chapter 7, we adopted the principle of virtual work and used it (in Section 7.6) to derive the unit-load theorem, which is applicable to linear or nonlinear structures of any shape. In this chapter and in the succeeding one, we shall consider the method of virtual work further, first with reference to trusses and later to beams and frames. The present chapter will also deal with evaluation of integrals for calculation of displacements by the method of virtual work.
