ABSTRACT
We have already seen that the knowledge of the magnitude of displacements in a structure is necessary in the analysis of statically indeterminate structures, and in the preceding two chapters we used, for the purpose, either the displacements due to forces or the forces induced by imposed displacements. Displacements are, of course, also of interest in design, and, in fact, in some cases the consideration of deflections under design loads may be the controlling factor in proportioning of members.
