Steel structures — Execution of structural steelwork — Part 1: General requirements and terms and definitions

This document defines general requirements for the execution of structural steelwork for:

— structural steel buildings;

— general structures, designed, fabricated, and erected in a manner similar to buildings with building-like load-resisting elements, e.g. support framing for equipment, tanks, vessels, and pipelines;

— crane-supporting structures;

— typical roadway and pedestrian bridges including those constructed using rolled sections, welded plate girders, or trusses (lattices).

This document applies to structures or fabricated components that are produced from:

— hot-rolled and cold-formed structural steel products up to and including a nominal yield strength of 700 MPa with a thickness of 3 mm and above;

— hot-finished and cold-formed structural steel hollow sections, up to and including a nominal yield strength of 700 MPa, including standard range and custom-made rolled products and hollow sections manufactured by welding.

This document also applies to steel components in composite steel and concrete structures, and in structures combining steel with other materials.

This document defines requirements independent of the type and shape of the steel structure, includi
