Subject description All engineers who wish to practise as civil engineers in Australia must have knowledge of structural design, including the behaviour and design of reinforced concrete (RC) and, to a lesser extent, of prestressed concrete (PSC) elements as parts of overall structures. This subject builds on the knowledge of statics, solid mechanics and structural analysis of indeterminate structures that the students have learnt in the previous structural strand subjects. Students learn about the behaviour and design of RC beams, slabs and columns and PSC beams, for both serviceability and strength. Initially, the students are introduced to the Limit State Design philosophy of Australian Standards for structural design and to the material properties of concrete, reinforcement and prestressing steel used for design. RC topics include uncracked section analysis of beams, cracked section analysis of beams (linear-elastic, Desayi-Krishnan, ultimate) for strength and design for strength to AS3600, serviceability design of beams, ductility of singly and doubly reinforced sections, design for shear, T-beams, approximate analysis and design of one-way, two-way slabs and flat slabs/plates, columns (interaction diagrams and slenderness effects), pad footings, cantilever retaining walls and reinforcement detailing. PSC beam topics include history, uncracked section analysis, equivalent loads, load-balancing, cracked section analysis (linear-elastic and ultimate), design for bending, shear, transfer, anchorage.

Subject learning objectives (SLOs) Upon successful completion of this subject students should be able to: 1. Discuss the behaviour and design of RC beams, slabs, columns, pad-footings, retaining walls and PSC beams, for both serviceability and strength 2. Apply the Limit State Design philosophy of Australian Standards for structural design 3. Discuss the material properties of concrete, reinforcement and prestressing steel 4. Discuss the behaviour, of RC flexural members, for Serviceability and for Strength at Ultimate, RC beams, slabs & columns, pad footings, and cantilevered retaining walls to AS3600 for Strength at Ultimate 5. Apply AS3600 to analysis, design and detailing of PSC flexural members for Serviceability and Strength

Teaching and learning strategies The teaching and learning strategies focus on: theoretical material; its application to professional and construction practice in structural design and lectures supplemented by notes, worked examples and practice problems. Students’ knowledge in this subject will be reinforced with design assignments and laboratory testing of concrete beams to failure. Finally, quizzes and examinations will thoroughly test the students’ knowledge in this subject to ensure only those students who can design concrete structures competently may proceed to the next design subject.

Content (topics) General – Limit State Design, loads. Reinforced concrete – introduction to reinforced concrete behaviour, uncracked and cracked section analyses, linear elastic and ultimate behaviour in beams, serviceability of beams and ultimate design for moment and shear in rectangular and T beams, one-way, two-way and flat slab analysis and design, punching shear, column design (stocky and slender), reinforcement detailing, footings, and retaining walls. Prestressed concrete – pre-stressing steel material properties, geometry, losses and effective prestress force, equivalent loads and load balancing techniques to analyse uncracked and cracked sections under linear-elastic conditions.
