PD 7974-3:2011 Application of fire safety engineering principles to the design of buildings. Structural response and fire spread beyond the enclosure of origin This Published Document ( PD 7974-3:2011 ) provides a framework for developing a rational methodology for design using a fire safety engineering approach through the application of scientific and engineering principles to the protection of people, property and the environment from fire. PD 7974-3:2011 considers the following issues:

The conditions within a fire enclosure and their potential to cause fire spread The thermal and mechanical response of the enclosure boundaries and its structure to the fire conditions The impact of the anticipated thermal and mechanical responses on adjacent enclosures and spaces The structural responses of loadbearing elements and their effect on structural stability, load transfer and acceptable damage according to the design and purpose of the building Fire following structural impact to the building.

PD 7974-3:2011 is one of a series of documents published under the Fire Standards Policy Committee, and is a supporting document to BS 7974 , Code of Practice on the Application of Fire Safety Engineering Principles to the Design of Buildings. Other documents in the series are:

PD 7974-0:  Guide to design framework and fire safety engineering procedures

PD 7974-1:  Initiation and development of fire within the enclosure of origin

PD 7974-2:  Spread of smoke and toxic gases within and beyond the enclosure of origin

PD 7974-4:  Detection of fire and activa...
