A Guide Fire on Protection Fire Protection and Performance-based and Performance-based Fire Engineering Fire Engineering<br />
Are fire-safety requirements more stringent for steel buildings than concrete<br />
buildings?<br />
The fi re-safety requirements are similar for both types of buildings. The only difference is the method<br />
of protection which depends on whether the building is constructed using steel or concrete.<br />
Fire resistance is a property of a particular building element which measures its ability to resist the<br />
spread of fire through the material characteristics of<br />
• stability (resistance to collapse or excessive deflection);<br />
• integrity (resistance to passage of flames and hot gases); and<br />
• insulation (resistance to excessive temperature rise on exposed face).<br />
Usually, fi re resistance of a building element is expressed in terms of the minimum period of time<br />
during which the building element would function satisfactorily while subject to a standard fi re test,<br />
measured in BS 476: part 20 to 23.<br />
It is the onus of the designer to accord additional and appropriate level of fi re protection to materials<br />
used in the building which do not meet the required rating of fi re resistance.<br />
