5 Introduction to resistance tables


EN 1993-1-1 unless otherwise noted

The design resistances given in the tables have been calculated using exact values of the section properties calculated from the specified dimensions. The values obtained have then been rounded to 3 significant figures.      

Design resistance tables are given for steel grade S355 (both hot finished and cold formed) and S420 (hot finished only).

The following partial factors for resistance in the relevant National Annexes have been used throughout the software for the calculation of the design resistances.

Table 5.1

Partial resistance factor Dutch, French & UK National Annexes German National Annex
γM0 for the resistance of cross sections 1.0 1.0
γM1 for the resistance of members 1.0 1.1

5.2Yield strength

The member resistance tables are based on the following values of yield strength fy

Table 5.2

EN 10210-1
EN 10219-1
Steel Grade Maximum Thickness less than or equal to (mm) Yield strength fy (N/mm2)
S355 16
S420 16 420

The above values are those given in the product standard EN 10210-1 for hot-finished hollow sections and EN 10219-1 for cold-formed hollow sections.
