Abstract

This paper describes the insulative value of spray-applied, cementitious and mineral-fiber fire resistive coatings for steel building columns. It presents results of high-temperature thermal property tests of the materials used as input to a two-dimensional heat flow analysis designed for predicting the fire resistance of hollow steel columns. The prediction is compared with actual fire test data. The influence of the thermal properties of the materials and their application thickness on fire resistance is discussed.
