This book examines the design of steel structures and defines the approaches for various design codes, including AISC, BS, and EC3. It also discusses the theoretical background for the design of different structural members and provides illustrative examples of each, as well as structural connections, base plates with anchor bolt designs, and more. In addition, best practices for on-site construction methods including receipt of materials, and quality control and assurance, and inspection are also presented. Both non-destructive testing and destructive testing methods are presented.
