Course extends the basic stiffness method of analysis developed in the pre-requisite courses. Fundamental principles of the stiffness method of analysis, with automatic assembly of the stiffness matrix for rigid jointed plane frames and space structures, are presented in some detail. Elastic instability of frames, and the design of continuous steel beams and portal frames using plastic methods will be undertaken. Analysis of flat plates and slabs using yield line theory, and an introduction to shells also covered. The course concludes with a brief outline of the finite element method of analysis, with computer-based applications forming an important practical component.
