AbstractThe influence of various significant parameters on the required structural fire protection of buildings is examined. In particular, the influence of the probability of the occurrence of fire, the size of the building, and the variation of fire loads and fire resistance of structures are considered. Expressions are given for the probability of failure of structures by fire and the fire loss expectation. By balancing costs and benefits, using probabilistic criteria, the justifiable fire protection measures in buildings can be determined in a rational way. It may be expected, therefore, that with information obtained in this way optimum fire protection measures can be determined more accurately than will be possible by present methods, which are entirely based on judgement and experience. How close the optimum measures can be approached depends to a large extent on the accuracy with which the values of the parameters that determine these measures are known.
