AbstractCanadian practice in structural fire protection is explained briefly and critically reviewed. Some major shortcomings are pointed out and discussed in the light of recent research and developments in the field. The mechanism of failure of the basic steel structural elements is examined with reference to the conventional "instantaneous deformation concept" and the newer "creep concept". It is shown that while the first concept can be applied legitimately to certain problems, the second is more realistic and applies to all problems. Other benefits accruing from the creep concept, such as the calculation of a critical temperature for an element, are also pointed out. To illustrate how a relatively complex problem can be simplified by judicial application of engineering methods, an analysis of the fire endurance of unprotected steel columns is presented. By comparison with computer analysis and experimental results it is evident that the simplified calculation yields acceptable accuracy from an engineering point of view. A building regulation for steel constructions used in Zurich, Switzerland, is described briefly to show how an engineering approach may be put into practice.
