STRUCTURAL DETAILING IN STEEL

Preface

This steel detailing manual has been prepared to provide practical and up to date information on various aspects of steel construction for educators, designers, draughtsmen, detailers, fabricators and all others who have an interest in structural steelwork.

The text covers the full scope of structural detailing in the UK, Europe and the USA. The text covers the fundamentals of drawing, continuing with draughting practice and connections, the types of fastenings and the conventional methods of detailing components. Individual case studies are included.

The types of structure covered represent the bulk of the typical fabricator's work in commercial and industrial buildings, bridges, tanks, hydraulic and offshore structures and power structures. Examples of steel detailing in CAD format are included in some of the chapters.

Many of the drawings included are typical and, with minimal alteration, can be adopted directly from the book and attached to individual drawings based on a special code.

This book should serve both as a primer for trainee detailers and as a reference manual for more experienced personnel. Engineers, architects and contractors will find the book useful for daily use and practice.
