BS EN 1993-1-2 deals with the design of steel structures for the accidental situation of fire exposure and is for use in conjunction with BS EN 1993-1-1 and BS EN 1991-1-2. It also identifies differences from, or supplements to, normal temperature design and deals with passive methods of fire protection. It gives principles and application rules for designing structures for specified requirements in respect of the load bearing function and the levels of performance.
BS EN 1993-1-2 describes the principles, requirements and rules for the structural design of steel buildings exposed to fire, including the following aspects:
- Design of steel structures for accidental exposure to fire
- Passive methods of fire protection
- Applies to steel structures that are required to fulfil this load bearing function, avoiding premature collapse due to fire
- Gives principles and application rules for designing structures for specified requirements in respect of the load bearing function and the levels of performance.
The methods given are applicable to any steel grade for which material properties at elevated temperatures are available, based on harmonized European standards.
