| Resumen: | (1) This document gives supplementary provisions that extend the application of EN 1993-1-1 and EN 1993-1-5 to the design of rolled and welded steel sections with various shapes of web openings. The following cases are considered: - rolled or welded beams with single or widely spaced web openings; - rolled or welded beams with closely spaced web openings; - cellular beams with circular openings made by cutting and re-welding two parts of steel sections that may be different in dimensions; - beams with hexagonal and sinusoidal openings made by cutting and re-welding two parts of steel sections that may be different in dimensions. (2) This document applies to uniform members with I or H profiles, which are symmetric about the weak axis. It does not apply to non-prismatic or curved beams although the same principles can apply. (3) This document applies to steel beams with web openings that are subjected to sagging (positive) or to hogging (negative) bending moments. (4) This document covers the verification of the resistance at the openings and their effects on the global behaviour of the beam, including lateral torsional buckling. (5) Alternative methods are presented for beams with circular openings and with sinusoidal openings in which the forces and resistances are calculated by increments around or along the openings and which are suitable for computer methods. (6) This document applies to web slenderness, hw/tw, not exceeding 121 |
