ABSTRACT

All the structures that are analysed in the present chapter are assumed to be in equilibrium. This is a fundamental assumption that is made in the structural design of most structural components, some of which can then be designed quite satisfactorily from statical considerations alone. Such structures are said to be statically determinate.

Most modem structures, however, cannot be solved by considerations of statics alone, as there are more unknown ‘forces’ than there are simultaneous equations obtained from observations of statical equilibrium. Such structures are said to be statically indeterminate, and analysis of this class of structure will not be carried out in this chapter.
