The Green Books
The Green Books gives essential guidance for structural steelwork connections for use in buildings. They have been produced by the SCI/BCSA Connections Group, which was established in 1987 to bring together academics, consultants and steelwork contractors to work on the development of authoritative design guides for structural steelwork connections. There are two publications for use in Eurocode design, and they may be downloaded here:
- SCI P358, Joints in steel construction: Simple joints to Eurocode 3 (2014 reprint)
- SCI P398, Joints in steel construction: Moment-resisting joints to Eurocode 3

| How to use the Green Book |
Main article: Simple connections
SCI P358 (2014 reprint) provides procedures for designing joints in steel-framed structures in accordance with BS EN 1993-1-8[1] and its accompanying National Annex[2], and with BS EN 1993-1-1[3] and its National Annex[4]. Connections between beams and columns using non-preloaded and preloaded bolts are included. Connections between beams and hot finished structural hollow section columns using the Flowdrill and Hollo-Bolt systems are also included. Design procedures are provided for:
- Beam to beam and beam to column connections
- Column splices
- Column bases
- Bracing connections
- Special connections
The revisions in the 2014 reprint include revised tying resistances for full depth end plates for deeper beams, revised resistances for RHS bases, an additional example using blind bolts, revised guidance for bracing connections and typographical corrections. Revisions are marked with a black line in the margin.
[top]Moment resisting connections
Main article: Moment resisting connections
SCI P398 provides methods for designing moment-resisting joints in accordance with Eurocode 3. The publication covers:
- Bolted end plate connections between beams and columns typically used in multi-storey frames
- Bolted end connections typically used in portal frames
- Bolted splice connections
- Welded connections between beams and columns
- Column bases
All connections described in procedures, examples and appendices are between I section members bending about their major axes. Nevertheless, the general principles presented here can be applied to moment-resisting connections between other member types.
