Book excerpt: The seventh edition of Simplified Design of Steel Structures is an excellent reference for architects and engineers who need information about the common uses of steel for the structures of buildings. The clear and concise format benefits readers who have limited backgrounds in mathematics and engineering. This new edition has been updated to reflect changes in standards, industry technology, and construction practices, including new research in the field, examples of general building structural systems, and the use of computers in structural design. Specifically, Load and Resistance Factor Design (LRFD) and Allowable Stress Design (ASD) are now covered.
