Objectives On completion of this subject the student should have the ability to design steel structures using both elastic and plastic methods; to understand the actual behaviour of structures under increasing loading until collapse; to analyse and design concrete slabs.
Synopsis Plastic design: plastic behaviour of simple structures, collapse load, plastic analysis of single span beams, continuous beams and portal frames; mechanism method, basic and combined collapse mechanisms, beam and sway mechanisms, plastic design to AS4100, second-order effect, amplification factor, plastic design of web. Limit analysis of general frames by computers, elastoplastic analysis, concept of plastic hinges. Composite construction; partial shear connection; shear connectors. Yield line analysis of slabs, yield line patterns, positive and negative yield lines, collapse load by energy method, applications to reinforced concrete slabs.
