Contemporary structural engineering design uses computer frame analysis software to determine the deflections, forces and bending moments in a structure due to a set of loads. These computer-generated results are then used in the application of code-based design methods. This course is not about structural design in general. It focuses on the particular knowledge and skills necessary to develop a correct computer model of a structure and on the interpretation and design application of information generated by the computer analysis. This is a highly practical and hands on course designed to develop responsible and informed proficiency in the use of computer analysis for structural design.

Structural engineering design is a continually evolving process. The development of computer analysis tools has had a massive impact on what engineers do in their day-to-day work. Twenty or thirty years ago structural engineers needed proficiency in a wide range of manual calculation methods to analyse structures. A set of "design calculations" at the time was likely to include extensive pages of detailed numerical workings. Some may argue that proficiency with such hand calculation methods remains useful to a design engineer, but such skills are no longer essential. What is essential is a sophisticated and informed understanding of how to model a structure in a computer so that the model conforms both with reality and with the expectations of the design codes. Using a process of learning by discovery, the student is guided through a series of discussions and investigative computer modelling exercises. These demonstrate how very minor modelling changes can lead to quite different "answers". The course looks in considerable detail at approximate methods of analysis that can be used both to enhance the students understanding of a structural system and as a check of computer analysis results. The course takes the opportunity to use computer modelling to investigate various structural phenomena and to consolidate and extend undergraduate understanding of design principles. There is significant emphasis placed on the development of meaningful computer aided design calculations that record modelling assumptions and the primary analysis output.

The course objectives define the student learning outcomes for a course. On completion of the course, students should be able to:

1. display proficiency in developing Space Gass models for the analysis of steel and reinforced concrete structures;
2. clearly document Space Gass models and results;
3. demonstrate a disciplined approach to structural modelling including self checking;
4. competently select and use a variety of approximate methods of analysis that may be used to check the validity of computer models;
5. demonstrate possession of a detailed appreciation and understanding of the compromises that are made in modelling of steel and reinforced concrete structures;
6. demonstrate a broad understanding of load estimation over the full range of building, civil, industrial and maritime type structures.
