Applied Structural Steel Design, Fourth Edition, continues to serve readers with a basic understanding of the strength and behavior of structural steel members and their interrelationships in simple structural systems. By providing content that is primarily an elementary, noncalculus, practical approach to the design and analysis of structural steel members, using numerous example problems and a step-by-step solution format, this text has remained true to its reader-friendly tradition. This edition, however, is a transitional text that bridges two methods of design that are currently being used: Load and Resistance Factor Design (LRFD) and Allowable Stress Design (ASD). Most engineering professionals agree that LRFD will become the dominant method in the future. However, since the traditional ASD method remains popular and practical and is still widely used, this text uses the traditional method while devoting entire chapters to the LRFD method. Key features of this edition: The use of a dual system of units: the customary American system as well as the SI system Expanded coverage of plastic design The use of "spreadsheet" homework problems throughout the bookSpiegel, Leonard is the author of 'Applied Structural Steel Design', published 2002 under ISBN 9780130889836 and ISBN 0130889830.
