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.
