This simple, practical, and concise guide to structural steel design – using the Load and Resistance Factor Design (LRFD) and the Allowable Strength Design (ASD) methods -- will equip the reader with the necessary skills for designing real-world structures. Following a holistic, project-based learning approach that bridges the gap between engineering education and professional practice, the design of each building component is presented in a way such that the reader can see how each element fits into the entire building design and construction process. Structural details and practical example exercises that realistically mirror what obtains in professional design practice are presented.
