The Handbook contains three parts and each member of the consortium of engineers who wrote it participated as author of the design rules, or author of the worked examples, or as editorial adviser representative of future users. Therefore, the consortium includes research engineers from CSIRO and the universities, and designers from large and small practices, and from the construction and fabrication industries. It is believed that the outcome is a book which is technically sound, and well-suited to use by a designer who wishes to make decisions with minimal design aids and only a handheld calculator. The users of this Handbook are assumed to be qualified to undertake structural design.
Part I of the book provides advice and rules in a structure similar to that of the first eleven sections of AS 4100. The chapter and paragraph numbers, titles, and notation, are kept as close to those of AS 4100 as possible so that designers can move readily from one document to the other in order to use the tier of their choice.
Chapter 1 sets out the scope and the limitations for the use of this Handbook and
Chapter 2 lists the relevant standards with which the materials should comply.
Chapter 3 describes the difference between Working Stress and Limit States Design and describes the classes of Limit States which should be anticipated. It also sets serviceability limits. Chapter 4 defines the methods of analysis for the purposes of obtaining design effects and displacements, the forms of construction, the assumptions for analysis and the limitations to the use of plastic analysis in this Handbook.
Chapters 5 to 8 provide rules and procedures for calculating the strength of members subjected to flexural, compressive, tensile and combined actions. Chapter 9 recognizes the fact that a large part of Australian structural practice uses a very limited and discrete range of fasteners. It therefore also contains simple tables of bolt and weld capacities, and of the relevant geometric data on hole sizes and edge distances.
Chapter 10 identifies circumstances under which brittle fracture is not likely to be a problem. Chapter 11 presents a simplified approach to design against fatigue. Advice is given only on situations where the stress range is constant and material is thin. The form of expression of the S-N curves is simplified by changing the definition of the detail category to reduce the number of ‘variables’ in the equations. The structure of
Chapter 11 is such that the designer will often be able quickly to exempt the detail from fatigue analysis with little or no computation. A more fundamental change in philosophy is that the Handbook enables the designer to calculate the life of the detail when it is fatigue-prone.
Part II is a set of design aids in the form of tables and charts derived from the dimensions of standard sections and from the rules in the Chapters of this Handbook. They speed up the design process and reduce the opportunity for computational error.
Part III consists of worked examples of the application of the rules in Part I. The examples are chosen to demonstrate realistic situations and have been worked out by designers in active commercial practice.
