Revision of the standard EN 1993‐1‐11 and background information

Abstract

Within the framework of the development of the second generation of Eurocode 3, Part 1‐11, related to the design of steel tension components, was completely revised.This paper introduces the main developments in the prEN 1993‐1‐11:2023 regarding the basis of design for the three groups of tension components: A ‐ Rods, B ‐ Ropes, and C ‐ Parallel strand or wire systems. For each of the three groups, complete information on the “Material”, “Ultimate limit state” (including fatigue) and “Serviceability limit state” requirements are provided. Improved formulas for the design of saddles and clamps are presented, including new saddle solutions for group C. Reference is made to the new group D ‐ Parallel wire tension components for suspended structures, included in new Annex C. Annex A “Product requirements for tension components” was completely revised to reflect modern testing requirements. Informative Annex B has been also updated with new figures that reflect the state of the art in tension elements and terminations.
