Application of fire safety engineering principles to the design of buildings - Structural response and fire spread beyond the enclosure of origin (Sub-system 3)

PD 7974-3:2003 considers the following issues:

• the conditions within a fire enclosure and their potential to cause fire spread by way of recognized mechanisms and routes;
• the thermal and mechanical responses of the enclosure boundaries and its structure to the fire conditions;
• the impact of these anticipated thermal and mechanical responses on adjacent enclosures and spaces;
• the structural responses of load-bearing elements and their effect on structural stability, load transfer and acceptable damage.
