1.1 Scope of FprEN 1993 1 1 (1) FprEN 1993 1 1 gives basic design rules for steel structures. (2) It also gives supplementary provisions for the structural design of steel buildings. These supplementary provisions are indicated by the letter “B” after the paragraph number, thus ( )B. 1.2 Assumptions (1) The assumptions of EN 1990 apply to FprEN 1993 1 1. (2) EN 1993 is intended to be used in conjunction with EN 1990, EN 1991 (all parts), the parts of EN 1992 to EN 1999 where steel structures or steel components are referred to within those documents, EN 1090 2, EN 1090 4 and ENs, EADs and ETAs for construction products relevant to steel structures.
