This Unit reviews the fundamental concepts of 'elastic' behaviour of reinforced concrete structures and introduces models of behaviour and methods of analysis related to the time-dependent effects of creep and shrinkage (at service loads). This Unit also examines the non-linear (strain-softening) behaviour of reinforced concrete and the related effects concerning the strength of statically-indeterminate reinforced concrete structures. In particular, this Unit examines the concepts of ductility, moment-redistribution and plastic design (for beams and slabs). Strut-and-tie modelling of reinforced concrete members is also described. Design guidelines will reflect requirements of the Australian Standards and Eurocodes. This Unit will provide students with the following knowledge and skills: understanding of the fundamental concepts and theoretical models concerning the time-dependent structural effects of concrete creep and shrinkage; ability to carry out calculations to estimate 'elastic' load-effects (stresses/strains/deformations) for reinforced concrete structures (at service loads), accounting for the time-dependent effects of concrete creep and shrinkage; understanding of the fundamental concepts and theoretical models of the strain-softening behaviour of reinforced concrete (in flexure); understanding of the fundamental concepts and numerical models of ductility and moment redistribution for reinforced concrete beams; ability to quantitatively assess the ductility and moment-redistribution capacity of reinforced concrete beams; understanding of the fundamental concepts and numerical models of plastic behaviour and design for reinforced concrete beams and slabs (including yield-line analysis); ability to determine the ultimate plastic load-carrying capacity of statically-indeterminate reinforced-concrete beams and slabs; ability to use strut-and-tie models of reinforced concrete behaviour.
