The fire resistance of cold formed sections is affected by the strength retention of the steel at elevated temperatures and the rate of heating of the thin steel section. Fire protection to cold formed sections may be of three forins depending on the materials used:
1. Planar protection as in floors and walls
2. Box protection
3. Profile protection.
Guidance is presented for the fire resistance of protected sections in floors or walls acting as compartment boundaries, i.e. planar protection. In this case, heat is applied from one side only and the floors or walls must satisfy the necessary insulation criterion. This guidance is based on manufacturers’ data for gypsum plasterboard and related materials.
The thickness of fire protection for conventional beams and columns is determined by using the method given in BS 5950: Part 8 for extending the existing data for hot rolled sections to cover the use of cold formed sections. Design tables are presented for typical materials and section sizes. A design summary is included at the rear of the publication which identifies the main fire protection requirements for cold formed steel sections in floors, walls and as individual beams and columns.
