48369 Structural Design 2

Requisite(s): 48359c Structural Design 1
Fields of practice: Civil Engineering program
Undergraduate
Subject coordinator: Chris Wilkinson

All engineers who wish to practise as civil engineers in Australia must have a competent knowledge of structural design to the relevant current Australian Standards, and a competent knowledge of structural analysis to allow the design to be done. Structural analysis is an integral part of the structural design process because it allows engineers to model the behaviour of structures under load and to determine the design actions induced by the applied loads. The prior structural subjects that students have completed have introduced them to statics, solid mechanics, methods of structural analysis, the structural behaviour of materials and structural design of reinforced concrete and timber elements. Structural design then builds on the prior fundamental knowledge of material properties and structural analysis and allows the engineer to design a safe and economical structure complying with the requirements of the relevant Australian Standards, based on his or her knowledge of and experience in structural behaviour.

Students learn about the structural behaviour and become competent in the structural design of steel elements (tension and compression members, beams, beam-columns and bolted and welded in-plane connections), reinforced concrete pad footings and cantilevered retaining walls and of prestressed concrete flexural elements in accordance with the relevant Australian Standards, AS4100-1998, AS3600-2001 and AS1170-2002. The competence gained in structural analysis assists students in gaining experience and competence in the structural design of these structural components.

Topics include: structural steel – material properties, tension and compression members, in-plane effective lengths, beam design (section moment capacity, lateral-torsional buckling, shear, web crippling, web buckling and three-plate girders, beam-columns, bolted and welded in-plane connections, fracture and fatigue behaviour and design; reinforced concrete – isolated pad footings and cantilevered retaining walls; prestressed concrete – introduction to prestressed concrete behaviour, load-balancing and equivalent load techniques, uncracked and cracked section analyses, linear elastic and ultimate behaviour in beams, serviceability of beams and ultimate strength design for moment and shear in beams, strength at transfer and end block reinforcement.

Assessment: Typically this subject will be assessed through a combination of assignments, a revision mini-quiz (RMQ), mid-semester quizzes, a short-answer quiz and a final examination.
