Download UoS Outline

Unit: CIVL5266: Steel Structures - Stability (6 CP)
Mode: Normal-Day
On Offer: Yes
Level: Postgraduate
Faculty/School: Civil Engineering
Unit Coordinator/s: DR Pham, Cao Hung
Session options: Semester 1
Versions for this Unit:
Campus: Camperdown/Darlington
Pre-Requisites: None.
Brief Handbook Description: This unit aims to:

- provide fundamental understanding at advanced level of the behaviour and design of hot-rolled/fabricated and cold-formed steel members;

- develop an understanding of the behaviour and design of steel connections in open and hollow sections.

- provide fundamental understanding of newly developed Direct Design Method (DDM) for analysis and design of structural systems;

It is anticipated that at the end of this unit of study students should:

- be familiar with the behaviour of steel structures at advanced level in selected areas, including design for local buckling and design for flexural-torsional buckling of columns and beams.

- have a sound knowledge of AS 4100 in the areas of section capacity determination of slender cross-sections, and flexural-torsional buckling of beams.

- have a sound knowledge of AS/NZS 4600 in the areas of section capacity determination of slender cross-sections, and flexural-torsional buckling of columns and beams.

- have knowledge of the use of FEM software in the design of structural systems.

- have the skills to assess the behaviour of specific connections.

- have an appreciation of some practical aspects of economical steel connection design.

Syllabus Summary:

Stability theory, Stability design to AS4100 and AS/NZS4600, Direct Design Method, Steel connection design.

Timetable: CIVL5266 Timetable
Time Commitment:
# Activity Name Hours per Week Sessions per Week Weeks per Semester
1 Lecture 2.00 2 13
2 Tutorial 2.00 2 13
3 Independent Study 4.00 1 13
T&L Activities: Tutorial: Most lectures will be followed by a tutorial session, lasting typically 1 hr. The tutorial problems aim at providing students a deeper understanding of the theory taught and competence in applying the theory to practical design. Students are highly advised to take advantage of the tutorial sessions, as it possible to complete a significant proportion of assignments during the allocated sessions.

Independent Study: Students should expect that they may have to allocate about 7 - 8 hours a week to the course, which includes about 2 hours of lectures, 2 hours of tutorials, and 3-4 hours outside university working on tutorial questions or assignments.

Learning outcomes are the key abilities and knowledge that will be assessed in this unit. They are listed according to the course goal supported by each. See Assessment Tab for details how each outcome is assessed.

Grading:
Grade Type Description
Standards Based Assessment Final grades in this unit are awarded at levels of HD for High Distinction, DI (previously D) for Distinction, CR for Credit, PS (previously P) for Pass and FA (previously F) for Fail as defined by University of Sydney Assessment Policy. Details of the Assessment Policy are available on the Policies website at http://sydney.edu.au/policies . Standards for grades in individual assessment tasks and the summative method for obtaining a final mark in the unit will be set out in a marking guide supplied by the unit coordinator.
Special Conditions to Pass UoS Special Conditions to Pass UoS: In addition to the normal 50 % total mark, the following criteria must be met to achieve a pass (a) final examination mark of at least 40%, (b) satisfactory submission of assignments. Students who do not meet all the criteria will not receive a pass in the unit of study, and regardless of their performance in individual components of the unit of study, will not receive a mark greater than 45 %. Students should note that satisfying the non-exam criteria does not necessarily imply that they have achieved “satisfactory progress".
Policies & Procedures: See the policies page of the faculty website at http://sydney.edu.au/engineering/student-policies/ for information regarding university policies and local provisions and procedures within the Faculty of Engineering and Information Technologies.
