ÖNORM B 1993-1-1

This Austrian Standard specifies national parameters to ÖNORM EN 1993-1-1 and shall be applied jointly with ÖNORM EN 1993-1-1 in Austria. EN 1993-1-1 gives basic design rules for steel structures with material thicknesses t bigger 3 mm. 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. The following subjects are dealt with in EN 1993-1-1: Section 1: General; Section 2: Basis of design; Section 3: Materials; Section 4: Durability; Section 5: Structural analysis; Section 6: Ultimate limit states; Section 7: Serviceability limit states. Sections 1 to 2 provide additional clauses to those given in EN 1990 ¿Basis of structural design¿. Section 3 deals with material properties of products made of low alloy structural steels. Section 4 gives general rules for durability. Section 5 refers to the structural analysis of structures, in which the members can be modelled with sufficient accuracy as line elements for global analysis. Section 6 gives detailed rules for the design of cross sections and members. Section 7 gives rules for serviceability.
