[top]SCI P363 Steel building design: Design data

How to use the Blue Book

The “Blue Book”, SCI P363, is the essential aid for the design of steelwork. Comprehensive section property data is provided as well as tables of member resistances, which are given for grades S275 and S355. This enables rapid selection of steel members in compression, bending and tension. Tables are also provided for combined bending and compression, web resistance and shear resistance. The latest edition provides resistances in accordance with the UK version of Eurocode 3 part 1-1[1], part 1-5[2], and part 1-8[3] together with their relevant UK National Annexes[4][5][6].

It also provides:

[top]Interactive "Blue Book"

An interactive version of the "Blue Book" is also available that includes design information in accordance with the relevant parts of both the Eurocodes and BS 5950. Produced by the SCI on behalf of Steel for Life, this comprehensive web-hosted eBlue Book covers the full range of both open sections and hollow sections (both hot finished and cold formed), and will not require any software to be installed on the host computer.

Design data is available for:

  • Universal beams, universal columns, bearing piles, and parallel flange channels to BS EN 10365[7]
  • Structural tees (cut from either universal beams or universal columns) to BS 4-1[8]
  • Equal and unequal angles to BS EN 10056[9]
  • Hot-finished structural hollow sections to BS EN 10210-2[10]
  • Cold-formed structural hollow sections to BS EN 10219-2[11]


Tables are provided for both S275 and S355 grades for open sections, S355 and S420 grades for hot-finished hollow sections, and S355 grade for cold-formed hollow sections. Comprehensive design data is also provided for bolts and welds, rolling tolerances are given, and there are comprehensive sets of explanatory notes for both the Eurocodes and BS 5950 data.

Note:

  • Tables of member resistances for S460 and HISTAR®  grades are available in ArcelorMittal's Orange Book
  • Tables of member resistances for hollow sections are also available in Tata Steel’s (tubes only) Blue Book
