CIVL5266: Steel Structures – Stability (2014 - Semester 1)
|Unit:||CIVL5266: Steel Structures - Stability (6 CP)|
DR Pham, Cao Hung
|Session options:||Semester 1|
|Versions for this Unit:|
|Brief Handbook Description:||Objectives:
This Unit aims to:
- provide fundamental understanding at advanced level of the behaviour and design steel structural members, notably members undergoing cross-sectional and/or global buckling.
- provide fundamental understanding of the methods available for determining buckling loads of structural members and elements, and explain how classical solutions to buckling problems are incorporated in national design standards for steel structures, including AS4100 and AS/NZS4600.
It is anticipated that at the end of this unit of study students will be familiar with the buckling behaviour of steel structures and will understand the methods available for determining buckling loads of structural members and cross-section. Students will have a good understanding of the stability design provisions for steel structures specified in the standards AS4100 and AS/NZS4600, and will be proficient in using software for calculating buckling loads.
Stability theory, Plate theory, Stability of plates and plate assemblies, Theory for thin-walled members in torsion and bi-axial bending, Stability of thin-walled members, Stability design to AS4100 and AS/NZS4600, Direct Strength Method.
|Assumed Knowledge:||There are no prerequisites for this unit of study but it is assumed that students are competent in the content covered in Structural Mechanics, Steel Structures, and Structural Analysis.|
Professor Rasmussen, Kim
DR Pham, Cao Hung
|Tutor/s:||Mr. John Hewitt and Mr. Morgan Rendall|
|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.
Attributes listed here represent the key course goals (see Course Map tab) designated for this unit. The list below describes how these attributes are developed through practice in the unit. See Learning Outcomes and Assessment tabs for details of how these attributes are assessed.
|Attribute Development Method||Attribute Developed|

For explanation of attributes and levels see Engineering & IT Graduate Outcomes Table.
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.Design (Level 5)
Assignment: Three assignments. Assignment 1: Local buckling (10%). Assigment 2: Flexural-torsional buckling (10%). Assignment 3: Design (10%).
Final Exam: Written three-hour exam at the end of the semester. Questions will be in the three main areas of study: Beam theory, flexural-torsional buckling and plate buckling-design.
