This text introduces the basic equations of the theory of
structures. Conventional presentations of these equations follow
the ideas of elastic analysis, introduced nearly two hundred years
ago. The present book is written against the background of advances
made in structural theory during the last fifty years, notably by
the introduction of so-called plastic theory. Tests on real
structures in the twentieth century revealed that structural states
predicted by elastic analysis cannot in fact be observed in
practice, whereas plastic ideas can be used to give accurate
estimates of strength. Strength is discussed in the first part of
this book without reference to equations of elastic deformation.
However, the designer is concerned also with stiffness, for which
elastic analysis is needed, and the standard equations (suitable,
for example, for computer programming) are presented. Finally,
stability is analyzed, which again is essentially an elastic
phenomenon, and it is shown that a higher factor of safety is
required to guard against buckling than that required to guarantee
straightforward strength. The emphasis throughout is on the
derivation and application of the structural equations, rather than
on details of their solution (nowadays best done by computer), and
the numerical examples are deliberately kept simple."
