This part of BS 5950 gives recommendations for the design of structural steelwork using hot rolled steel sections, flats, plates, hot finished structural hollow sections and cold formed structural hollow sections, in buildings and allied structures not specifically covered by other standards.
Detailed recommendations for practical direct application of “second order” methods of global analysis (based on the final deformed geometry of the frame), including allowances for geometrical imperfections and residual stresses, strain hardening, the relationship between member stability and frame stability and appropriate failure criteria, are beyond the scope of this document. However, such use is not precluded provided that appropriate allowances are made for these considerations (see 5.1.1).
The test procedures of 7.1.2 are intended only for steel structures within the scope of this part of BS 5950. Other cases are covered in Section 3.1 or Parts 4, 5, 6 and 9 of BS 5950 as appropriate.
