PREFACE TO THE

FIRST EDITION

The purpose of this book is to enlighten humanity and contribute to the gen-eral betterment of this orb that we call home Failing that, we will settle for giving engineers enough guidance in the use of aluminum that they will feel confident designing with it The Aluminum Association, an industry

associ-ation of aluminum producers, publishes the Specificassoci-ations for Aluminum

Structures (hereafter called the Aluminum Specifications), which are the

gen-erally accepted criteria for the design of aluminum structures Our book is

keyed to the sixth edition of the Aluminum Specifications, and readers should

have access to it

Structural engineering may be regarded as the practice of analyzing and designing structures The analysis process resolves the loads applied to the structure into the resulting forces and moments in the components of the structure Structural design is, then, the sizing of the structure’s components

to safely sustain these forces and moments Academic curricula typically train students in structural analysis, as well as in the design methods appropriate

to common materials of construction (i.e., steel, concrete, and perhaps timber), and many excellent texts on these subjects are available We assume that the reader is already well versed in structural analysis and acquainted with steel design Our objective is to expand readers’ design capability beyond steel, and to present aluminum as another material of construction

While this text is keyed to the Aluminum Specifications, it is also organized

to parallel steel design practice We compare the requirements of the

Alu-minum Specifications to the provisions for the design of steel structures found

in the American Institute of Steel Construction (AISC) Manual of Steel

Con-struction Those design requirements and considerations that are particular to aluminum, then, are presented in the context of the steel design background that we assume on the part of the reader

In addition to bridging the gap between the familiar old state of steel and the exciting new realm of aluminum, we also seek to bridge the gap between the theoretical and the real worlds We recognize that one of the greatest difficulties in the transition from student to practitioner is knowing how to

apply the design methods in ‘‘the book’’ to real-life problems Whether that book is a text or an industry specification, it often seems that the problem at hand does not neatly fit into any of the categories given We include a step-by-step design process for real-world applications If our steps do not spare readers from a 12-step program, then their problems are beyond the scope of this text

PREFACE TO THE

SECOND EDITION

We were frankly surprised by the reaction to the first edition of this book

While it never threatened to reach the New York Times best seller list, the

favorable comments were more numerous and heartfelt than we had expected When a reader wrote that ‘‘you will be pleased to know that your book is rapidly becoming dog-eared as it is one of the most popular books in our library,’’ we knew we had achieved our goal What may have been the most surprising was the international notice the book received, including a Japanese translation and very favorable European reviews All this almost made up for the work it took to write it

Once we’d milked the acclaim for all we could, it was time to think about

a second edition The Aluminum Association forced our hand when it revised

the Specification for Aluminum Structures in the 2000 edition of the Aluminum

Design Manual Since this book is a guide to the Specification, an update was due The changes to the Specification are more than cosmetic, such as chang-ing the title to the schang-ingular ‘‘Specification.’’ They include changes to tension

limit states, design compressive strengths for yielding, design bearing stresses, slip-critical connections, screw pull-out strengths, and others, as well as met-rication of mechanical properties We’ve revised our text accordingly and metricated it, too, although we haven’t been pedantic about metrication in order to preserve readability We’ve also added the benefit of what is, we hope, additional wisdom gained from experience since the first edition Since

the Specification continues to be a living document, we’re dealing with a

moving target, but that keeps life interesting

We welcome readers’ comments—this time with slightly less trepidation than before It’s also easier now since this time we have an e-mail address: tgb@mindspring.com Thanks for your interest in aluminum and our book
