An engineering evaluation method of fire resistance performance of structural members is proposed by applying the multiple regression method to the formulation of the heat balance equation for the insulation. The heat balance equation is integrated with respect to time from the beginning to the time when the maximum temperature appears at the structural member so that fire resistance performance can be evaluated by judging if this maximum temperature reaches a threshold temperature. Parameters in the heat balance equation are quantified partly by substituting thermal properties of the related materials and partly by applying the multiple regression method to the results of the standard fire resistance tests. Effectiveness of this evaluation method was verified through its application to the results of 60 fire-resistance tests on steel members insulated with rockwool.
