This website presents design data derived in accordance with the following Parts of Eurocode 3 and their National Annexes:

  • EN1993-1-1:2005: Design of steel structures. Part 1-1: General rules and rules for buildings.
  • EN1993-1-5:2006: Design of steel structures. Part 1-5: Plated structural elements.

Where these Parts do not give all the necessary expressions for the evaluation of data, reference is made to other published sources in the General Notes.

The resistances in this website have been calculated using the partial factors for resistance given in the National Annexes for the Eurocodes. The partial factors are listed in Section 5.1 of the General Notes. The other parameters given in the National Annex that have been used when calculating member resistances are given in the relevant section of this website.

The following structural sections are covered in this website:

  • Hot-finished structural hollow sections to EN10210-2.
  • Cold-formed structural hollow sections to EN10219-2.

 This website also provides design data for Celsius®355 range derived in accordance with BS 5950.
