Development of calculation methods for the design of structural fire protection

In this country, as well as in most others, the level of structural fire protection is set by the regulatory authorities, in terms of a specified fire resistance period. The engineer must demonstrate that each element of structure would survive for the required period if it were subjected to the standard fire resistance test of BS476. This is normally demonstrated by using tabular data, such as the deemed‐to‐satisfy tables in the Building Regulations, or by obtaining a report of a test of a replica of the particular element.
