Section classification (ULS) (Composite beams: BS 5950)

For section classification purposes the true section is used. Tekla Structural Designer classifies the section in accordance with the requirements of BS 5950-1:2000 except where specifically modified by those of BS 5950-3.1:1990+A1:2010.

There are a small number of sections which fail to meet a classification of compact at the composite stage. Although BS 5950-3.1:1990+A1:2010 covers the design of such members they are not allowed in this release of Tekla Structural Designer.
