The Steel Construction Institute (SCI) P358 "Green Book" provides standardized design procedures for nominally pinned structural steel connections, ensuring compliance with Eurocode 3 for shear and axial loads. It covers common connection types—flexible end plates, fin plates, and double angle cleats—to facilitate safe and economical building construction. For more details, visit SteelConstruction.info.

Step 4: Check detailing rules
The Green Book also gives minimum/maximum:
Do you need help understanding a specific failure mode check (like block tearing)? Are you transitioning from BS 5950 to Eurocodes?
. These books provide standardized design procedures, resistances, and detailing rules for connections in braced frames.
- Finding: The Green Book's tabulated plate thickness for a 50-kip load is 1/2" (12.7mm). Optimization shows 3/8" (9.5mm) works with 98% utilization.
- Waste: 33% more steel per tab.
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.
The current edition (SCI P358) aligns with:
7. Alternative (If you cannot access the PDF)
You can design simple steel connections using:
The Green Book focuses on "simple" joints that primarily transmit vertical shear and axial forces while allowing for negligible moment resistance . Key connection types include:
