This brochure has been produced to assist Structural Engineers and Designers who use Hot finished Structural Hollow Sections whose section properties comply with BS 4848 : Part 2 (Ref 1) and whose Steel qualities comply with EN 102 10-l (Ref 2) to design using the Limit State basis as covered by BS 5950 : Part 1 (Ref 3).
It is important for designers to recognise that hollow sections, unlike their rolled open section counterparts, can be produced by a hot or cold forming process. The process of cold forming produces different mechanical properties in the section to that of hot forming and a reduction in the sectional properties used in design.
Designers wishing to use cold formed hollow sections should design in accordance with the appropriate cold formed standard and with the sectional properties as given in BS 6363 (Ref 4). Further guidance is given in British Steels Tubes & Pipes publication TD369 - ‘Cold Formed Hollow Sections’. In addition to the information contained in this publication, further assistance and design guidance is given in companion British Steel Tubes & Pipes publications (references 16 to 21) and the Steel Construction Institute (references 8 to 15) publications as given in Appendix A.
