Steel is a popular construction material in the US for various structures. The design of steel structures has evolved from Allowable Stress Design to more rational and economical procedures like AISC-LRFD. This course is based on AISC-LRFD and aims to provide an overview of modern procedures for the design and erection of structural steel buildings. It is suitable for civil engineers involved in design, fabrication, and supervision, and will provide practical examples to help designers create safe, economical, and constructible steel systems.
