AbstractIn this report, an attempt is made to develop temperature criteria for the fall-off of gypsum board layers in floor assemblies tested under standard fire conditions that can be used in the development of mathematical models for predicting the fire resistance of floor assemblies with lightweight framing. Results from eighty standard fire tests on floor assemblies protected with either one or two layers of gypsum board were classified into categories based on various parameters affecting the fire performance of gypsum board.
