Concrete Structures - Strength & Service (CIVL5269)

UNIT OF STUDY

Objectives: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. Outcomes: 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
