This guide explains the American Institute for Steel Construction (AISC) Load and Resistance Factor Design (LRFD) Specifications and Commentary, enabling readers to conform with and profit from the design aids and tables in the AISC Manuals of Steel Construction, Volumes I and II. It provides readers with specification interpretations, analysis and design examples, and graphs providing ready-made solutions to complex code formulas. Features of this practical volume include quick and economical beam selection tables, detailed truss design examples, and coefficients for shears, movements and points of inflection. It contains a variety of numerical examples, along with discussions of material specifications. The design requirements included in the LRFD specifications are arranged in an accessible manner, making it easy to pinpoint the design of specific elements. This resource offers structural engineers the material necessary for designing efficient structural steel buildings. Engineering students in related courses should find this book useful for understanding and becoming acclimated with the AISC and LRFD standard design practices.
