Structural Engineering 2
Unit code: ENB375
Contact hours: 4 per week
Credit points: 12
Information about fees and unit costs
This unit considers the following: limit states design of steel structures; buckling and ultimate strength behaviour of steel structures; tension members, compression members; local and global buckling (flexural and flexural torsional buckling modes) concepts as applied to compression members and beams; effective lengths of compression members and beams; design of beams; effect of lateral restraints on buckling; web stresses including web crippling and buckling; beam-columns; bolted and welded connections; unsymmetric bending of beams including principal second moments of area; shear stresses in beams of thin-walled open cross-sections and their shear centres. Most cold-formed steel sections are unsymmetric and hence the latter topics are useful in steel design.

Sample subject outline - Semester 1 2013
Note: Subject outlines often change before the semester begins. Below is a sample outline.
Rationale
An engineer must have the ability to analyse and design buildings, bridges, cranes, dams, power stations, transmission towers, aircrafts, etc. and an understanding of their behaviour under various loadings. Most of these structures are constructed in steel since it is one of the very efficient civil engineering materials that is also suitable for sustainable construction practice. Therefore a good knowledge and understanding of the behaviour, analysis and design of steel structures is important for civil engineers. This unit follows the first introductory unit in Structural Engineering and provides the basic knowledge and skills required for this purpose. It also includes some of the basic structural mechanics theories such as member buckling theories, unsymmetric bending, shear stresses and shear centres. These are all essential principles for further studies in a number of areas throughout the remainder of the course for you to become a competent civil/structural engineer.
Aims
The aim of this unit is to help you learn advanced structural mechanics theories and to gain a solid foundation in the behaviour and limit states design of steel structures.
Objectives
On completion of this unit you should be able to:
- Apply the limit states design method to steel structures including loads, load factors and capacity factors, the behaviour of the structural elements of steel structures (tension and compression members, beams, beam-columns & connections).
- Apply buckling theories to steel structural problems and relate the behavioural characteristics to the design rules in Australian steel structures standards.
- Calculate load paths, analyse simple structural systems and apply relevant design rules to design safe and efficient steel structural elements as part of a more complex structural system.
- Apply advanced structural mechanics principles to practical structural problems through unsymmetric bending theory, shear stresses and shear centre.

Approaches to Teaching and Learning
The unit will use lectures and tutorial sessions provided by experts in the fields of steel structures and structural mechanics (QUT and Australian Steel Institute staff), excellent resource materials including study notes and advanced technology videotapes consisting of computer and experimental simulations, innovative projects involving analysis, design and testing of steel columns and design of simple structures, web-based interactive study materials and E-mail communications.
Learning approaches include project based, experiential and team based learning.
Week 4 is a formative assessment.
Assessment
The assessment will comprise formative assessment tasks (to help you understand how you are progressing in this unit) and summative assessment (to grade your work against expected learning outcomes). Assessment tasks include problem solving exercises, a group project and an exam.
QUT's Assessment Policy is at MOPP c/5.1Feedback on your assessments will be given to you by your lecturer and tutors during lecture and tutorial classes and via email and Blackboard including written comments on problems and project work.

Academic Honesty
QUT is committed to maintaining high academic standards to protect the value of its qualifications. To assist you in assuring the academic integrity of your assessment you are encouraged to make use of the support materials and services available to help you consider and check your assessment items. Important information about the university's approach to academic integrity of assessment is on your unit Blackboard site.
A breach of academic integrity is regarded as Student Misconduct and can lead to the imposition of penalties.
Resource materials
Relevant and useful resource materials will be made available via Blackboard. Details of specific design handbooks will be advised at the commencement of this unit.
Risk assessment statement
You will undertake lectures and tutorials in the traditional classrooms and lecture theatres. As such, there are no extraordinary workplace health and safety issues associated with these components of the unit.
