First Published in 2017. An architect is not usually responsible for producing detailed structural calculations and drawings, unless the building concerned is very small and simple. Where the architect can be most effective in the field of structural design is in the clarity of the manner in which suggested solutions, in the form of schematic designs, are put to a structural engineer. It is vital that an architect can propose forms from which the structural engineer need not deviate, to the extent that the original design concept is violated. It is also important that he or she is able to make an informed and rational choice between apparently unrelated structural systems. The theme of this book therefore arises from the necessity for an architect to possess an extensive structural vocabulary, based on a clear understanding of the relevant underlying principles. Although written mainly for practising architects, it is hoped that the book will also provide a fresh perspective on the subject for building surveyors as well as for civil and structural engineers.
