Predicting the temperature of the structure

This depends on the location, the section factor and any protection applied. The temperatures attained by unprotected steel members can be determined using heat transfer relationships given in BS EN 1991-1-2 and BS EN 1993-1-2. In BS 5950 Part 8(14) the temperatures attained in a standard fire test are also given in tabular format. These are provided for fire ratings from 15 to 60 minutes. The temperatures attained by protected members can also be calculated according to BS EN 1993-1-2. In addition, temperatures can also be calculated using bespoke models calibrated against actual test results.
