The "Green Book" is designed for the "Simple Method" of structural design, which applies to braced frames where connections primarily carry shear and axial loads . It covers a wide range of connection types you'll encounter on a typical building project, including:
1. SCI P358: Joints in Steel Construction – Simple Joints to Eurocode 3
| Connection Type | Typical Use | Failure Modes | | :--- | :--- | :--- | | | Beam-to-column web or flange; beam-to-beam | Bolt shear/bearing, plate tearing, weld failure, block tearing. | | Full-Depth End Plate | Beam-to-column flange (high shear) | Bolt tension (prying action), plate bending, weld failure. | | Flexible End Plate | Beam-to-column web (light to medium shear) | Plate yielding, bolt shear, weld rupture. |
This volume covers nominally pinned connections. These joints primarily transfer vertical shear forces and must accommodate accidental tying forces without developing significant bending moments.
The Green Book provides maximum and minimum spacings. Spacing bolts too far apart increases prying forces. Spacing them too close leads to the "block tearing" failure between the bolt hole and the plate edge.
