- Structural Hollow Sections (S.H.S.)
- Abstract
- Fire protection of structural steelwork is usually achieved by cladding. As an alternative means of protection, W.S. Atkins and Partners proposed that Structural Hollow Sections (S.H.S.) should be filled with water. An unprotected S.H.S. would have a fire resistance of about 10 minutes. The principle of water filling as a means of fire protection is that the latent heat of vaporization would absorb the heat transmitted to the steel and keep it relativley cool. If the members were maintained full of water during a fire, it is almost certain that their fire resistance would be unlimited. This is the principle of the 'Multin' system. The present investigation is aimed at measuring the fire resistance of members that are slef-contained to avoid the complication and expense of a means of replenishing the water. A detailed study of the implementation of this system to actual building is not part of the Phase of the study.
