ABSTRACT

In Chapter 6, we discussed the slope-deflection equations that prove useful for the analysis of relatively simple statically indeterminate beams and frames. In Chapter 8, we discussed the force method (or flexibility method) and demonstrated that it too proved to be a convenient approach for the analysis of simple indeterminate members with one or two redundancies. In this chapter, we will consider a method of analysis that falls under the category of the displacement (or stiffness) method. The particularity of the displacement method is that the problem is formulated in terms of unknown displacements that, once determined, enable the entire structural model to be established. Displacement methods are usually the most convenient approaches for the analysis of indeterminate structures with more than one or two redundant reactions.
