Abstract(s)
The main objective of this work is to verify the fire resistance of unprotected (W-W-W) wood-towood
connections and compare the results with protected connections using gypsum
plasterboard. According Eurocode 5, part 1-2 the connections could be protected by the addition
of wood panelling, wood-based panels or gypsum plasterboard type A, H or F. To obtain
conclusions according the application of different type of gypsum plasterboard in the designed
W-W-W connections in different densities material, numerical models were building to verify the
level of protection in fire action. The wood behaviour varies with temperature and its influences
the progressively properties degradation. After fire exposure, it is need to determine if the charred
wood connections will rest safe for use. Design methods require the use of analytical
methodologies and computational modelling to predict the fire exposure and the components
capacity to resist to this action. Results of the temperature field in the studied connections under
fire will be presented, with the measured char layer in unprotected members and comparing the
protected efficiency with different types of gypsum plasterboard.
