Here is the "full story" on this essential manual, what it contains, why it is referred to by its cover color, and how it is used in the industry. Formal Title: Joints in Steel Construction: Simple Connections Publisher: The Steel Construction Institute (SCI) and the British Constructional Steelwork Association (BCSA). The "Green Book" Moniker: In the construction industry, major reference manuals are often nicknamed by the color of their covers to save time. Just as the steel design manual is "The Blue Book" and the Eurocode implementation guides were the "Red Books," this specific guide for connections has sported a green cover for decades, earning it the permanent nickname. The Purpose: Why Does It Exist? Before the Green Book, structural engineers had to calculate every single bolt, weld, and plate capacity from first principles using code equations (like BS 5950 or Eurocode 3). This was time-consuming and prone to inconsistency. Different engineers might design the exact same beam-to-column connection in slightly different ways, leading to confusion in fabrication shops.
