    Abstract

    Two techniques are outlined for designing buildings to meet prescribed probabilities of structural failure in fire. They require input information for seven variables; three of these variables, fire load, ventilation, and (experimentally determined) fire resistance, are random variables. Information on the randomness of the first and third variables is available. The second variable, ventilation, is taken into account with its most adverse value.
