CIVL5269: CONCRETE STRUCTURES: SERVICEABILITY AND STRENGTHSemester 2, 2014 | 6 Credit Points | Mode: Normal-Day Sessions Valid: Semester 2 Coordinator(s): Stuart ReidWARNING: This unit version is currently under review and is subject to change!

1. INTRODUCTION

Objectives:

This Unit reviews the fundamental concepts of ‘elastic’ behaviour of reinforced concrete structures andintroduces models of behaviour and methods of analysis related to the time-dependent effects of creep andshrinkage (at service loads). This Unit also examines the non-linear (strain-softening) behaviour of reinforcedconcrete and the related effects concerning the strength of statically-indeterminate reinforced concretestructures. 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 structuraleffects of concrete creep and shrinkage

* ability to carry out calculations to estimate ‘elastic’ load-effects (stresses/strains/deformations) for reinforcedconcrete 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 ofreinforced concrete (in flexure)

* understanding of the fundamental concepts and numerical models of ductility and moment redistribution forreinforced 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 forreinforced concrete beams and slabs (including yield-line analysis).

* ability to determine the ultimate plastic load-carrying capacity of statically-indeterminate reinforced-concretebeams and slabs

* ability to use strut-and-tie models of reinforced concrete behaviour
