The UK National Annex to Eurocode 3, titled "Design of steel structures. General rules. Structural fire design," provides guidance for designing steel structures exposed to fire. It is used in conjunction with other Eurocodes such as BS EN 1993-1-1 and BS EN 1991-1-2. The standard addresses the design of steel structures under accidental fire exposure and covers passive methods of fire protection.

The standard aims to ensure that steel structures maintain their load-bearing function and avoid premature collapse during a fire. It presents principles and application rules for designing structures based on specific requirements and performance levels. These methods are applicable to steel grades with available material properties at elevated temperatures, following harmonized European standards.

The UK National Annex to Eurocode 3 includes decisions for the National Determined Parameters, as described in various subclauses of the standard. It also provides guidance on the status of informative annexes within the standard and references to non-contradictory complementary information (NCCI). This Annex serves as a reference document for designers and engineers involved in the structural fire design of steel buildings in the UK.
