Structural design is concerned with buildings and other structures such as bridges. A structural design engineer is required to make decisions about how buildings and other structures will be built such that they will perform satisfactorily and will not rapidly deteriorate, deflect excessively or in the worst event, collapse. The design engineer makes decisions about the general arrangement of the structural members, the materials of which they are made, their size and how they are connected. Structural designers make use of information about materials and construction processes together with various analytical techniques to assist them in making the correct decisions about how structures should be built. In pre-requisite courses students will have already acquired some of this knowledge. In particular, they have learnt how to analyse structures to determine such things as bending moments, deflections and stresses. In this course they will revise, consolidate and extend these topics and use them to assist in the design of structures. The course concentrates on estimating the loads which a structure may be required to carry, designing individual members in steel and timber. Specific code provisions applicable to design of timber and steel together with load estimation are discussed in detail in this course.

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

1. present defining diagrams and associated discussions and/or calculations relating to structural design in a manner that communicates the logic of the underlying phenomena and processes;
2. map out the major steps in the total design process;
3. extract separable structural elements from simple buildings and model the supports, restraints, continuity and loading conditions on such elements in terms of line load diagrams;
4. utilise approximate analysis techniques to determine design load effects on indeterminate structures;
5. explain the logic behind, and apply limit state design;
6. use relevant industry standards to evaluate structural engineering loads;
7. determine approximate member sizes in steel and timber for simple situations;
8. differentiate the material characteristics of different types of timber based on testing result and also from those of steel, and determine timber member sizes to industry standards for tension elements, beams and columns;
9. determine member sizes to industry standards for structural steel tension elements, pure compression elements, and beams;
10. explain nominated aspects of relevant national building codes.
