Statistical verification of partial factors for buildings according to Eurocode EN 1993-1-1 Annex E

General information

50.60     Sep 21, 2023



Technical Specification

91.010.30     91.080.13  


This document provides requirements for the statistical distribution of material properties and dimensional parameters of structural steel products, allowing the proof of consistency of the safety approach of the properties of the product standards compared to those of the design standards for the design of steel buildings. It also describes the evaluation procedures for the verification of the compliance of structural steels with these requirements.
This document applies for the following structural steel products intended for buildings: hot rolled and welded I- and H-sections, hot rolled plates rolled on a reversing mill, sheets/plates cut from hot-rolled wide strip and hot finished and cold formed welded structural hollow sections.
It is intended to be used as a background document to support the assessment of the partial factors for steel constructions (as detailed in EN 1993-1-1).
This document can be used for neither product ordering nor certification.
NOTE The background of statistical requirements on mechanical properties and geometrical parameters is detailed in EN 1993-1-1:2022, Annex E.
