ABSTRACT

The nominal values of the yield strength fy and the ultimate strength fu for structural steel may be taken from Table 3.1 in EN 1993-1-1 or direct from the product standard, that is EN 10025 for hot-rolled sections. The UK National Annex states that the nominal values for structural steel should be obtained from the product standard. The product standards give more steps in the reduction of strength with an increasing thickness of the product.
