Welcome to Steel Structures 1 for Semester 2 2009. This website is modified during the semester with the links below for tutorials and assignments becoming active after they are distributed in class.

The first lecture will be held on Tuesday 28 July in the Civil Engineering Drawing Office.

There have already been some questions concerning your lab sessions. Your timetables will list a lab session on either Wednesday or Thursday afternoons 2 - 4 pm. Firstly note that there are only two sessions to attend (not every week). More information will be circulated once the semester begins.

The lecture notes for the course will be available from the University Printing Service soon (not the Coop Bookshop). You will also need the Australian Standard AS 4100 - but most of you should have purchased the student standards handbook, HB2.2, last year for Structural Concepts - this is OK. You should also have the AISC book "Economical Structural Steelwork" distributed last year in Introduction to Structural Concepts and Design.

Structural Analysis is an elective for you this term. Some of may not have enrolled in it. There will be some slight disadvantage for those students - but since the assignments that involve using computer structural analysis programs are group assignments - you can team up with someone who is doing analysis. I will suggest (in my completely unbiased structural engineering way) that structural analysis is the most important of the 4 electives offered to you this semester, so if you are still deciding on your 3rd year electives, I would strongly recommend that you pick analysis.

There are student versions of the analysis programs Microstran available for you to use at home - visit http://www.civil.usyd.edu.au/current/undergraduate/software.shtml

You have all done Structural Mechanics, and I expect that you are competent in drawing simple BMDs and SFDs for statically determinant structures. I would also suggest that it would be a good idea to revise the chapter on bending from structural mechanics - so that you can work out stress and strain, and understand the terms such as I, Z, J and r.

I hope that you enjoy this unit of study and you find it interesting, challenging and informative, and that this year is successful both academically and in any other endeavours that you undertake.

General Information

  • Course Information Sheet - Download PDF
  • Weekly email bulletins: Each week, enrolled students will receive an email update summarising the content of the week, and information on upcoming content and assignments.  It will contain suggestions on tutorial questions, assignments and quizzes.  Use this as an important part of your study program.  Archived messages are kept on the WebCT site.
  • Want to ask a question? Students should ask all general and technical questions on the WebCT bulletin board. Other students are encouraged to answer as well. The lecturer will try to answer any questions each day. Students should only email the lecturer directly for questions of a personal nature.
