Module Aim: (1) To develop an understanding of the stress and strain behaviour of elastic and elastoplastic materials under axial, flexural and torsional loads. (2) To develop an understanding of basic structural concepts relevant to civil engineering structures. (3) To develop the skills required to analyse the force distributions on simple, encastre and continuous beams and plane trusses. (4) To develop an understanding of behaviour of struts (5) To introduce the concepts of real work, virtual work and strain energy and apply them to finding deflections and analysing statically indeterminate beams and trusses.
