Charring of Protected Wood Studs

摘要

The charring of wood studs has been studied in the cone calorimeter at constant heat flux 50 kW/m~2 and compared to data form full-scale furnace wall tests. The wood studs were unprotected by gypsum plasterboards on the exposed side. Similar charring depths were found and the data analysed mainly in terms of fire exposure. A simple small-scale technique was developed to measure the heat transfer through protective boards and the charring depth of wood studs. These properties are essential for the load bearing capacity of wood frame structures.
