fire detection & Suppression

Large-scale fire tests, observations of actual building fires and stuctural fire engineering studies have shown that the fire performance of real buildings can be much better than expected.

Research has shown that standard fire resistance requirements typically over-specify the fire protection needed. It is clear that there are large reserves of fire resistance in modern steel-framed buildings and that standard fire resistance tests on single unrestrained members do not provide a satisfactory indicator of the performance of such structures.

The tragic events of 11th September 2001 showed that a structural collapse might be caused by a combination of an initial impact followed by a severe fire. However, detailed investigation of the structural behaviour of high-rise buildings subjected to such events, has facilitated a better understanding of the principal cause of the ultimate structural collapse – and the most effective forms of mitigation.

fire protection cost saving

Applied fire protection is costly, can be unsightly and often delays building completion, normally has a limited life and will need maintenance. This is especially the case where the protection is exposed to mechanical damage.

Applied fire protection can substantially increase costs during the lifetime of the building. Stuctural fire engineering techniques can eliminate as much as half the applied fire protection normally imposed by compliance with standard guidance.

hnla Fire Engineering uses software developed ,by the Fire Safety Engineering Research and Technology Centre (FireSERT) one of the most sophisticated packages available for structural fire engineering. The software, developed by the University of Ulster includes a unique model that is able to address compartmentation issues.
