N2 - This paper presents the results from an experimental study on the behaviour of gypsum board protected, wood-stud shear wall assemblies. The experimental study consisted of fire resistance tests on 12 full-scale wall assemblies. The factors investigated included effects of placement and type of shear membrane, insulation type, presence of resilient channels and load intensity on the fire resistance of such assemblies. The test results show that the shear membrane placement and insulation type, significantly influence the fire resistance of wood-stud shear walls. The results of this and other studies were used to develop a model for predicting the fire resistance of wood-stud wall assemblies. The model couples a heat transfer sub-model and a structural sub-model. The heat transfer sub-model predicts the temperature profile inside the wood-stud assembly and the time to insulation failure. The structural sub-model uses the temperature profile to calculate the deflection of the studs and the time to structural failure of the assembly. A comparison with test results indicates that the model predictions are reasonable.
