| dc.description.abstract | The next generation of the Eurocode EN 1995-1-2 modifies the Effective Cross-Section Method (ECSM), where an adequate char depth reduces the initial timber cross-section. This char depth is based on the notional char layer (European Charring Model-ECM) and a zero-strength layer to compensate for the loss of strength and stiffness of heated but uncharred wood. The remaining effective cross-section has wood's strength and stiffness properties at room temperature and may be used to determine the load-bearing capacity. This investigation deals with gypsum-protected Glue Laminated Timber (GLT) columns under fire. The finite element method is also used to determine the fire resistance time based on a geometrical and material nonlinear analysis (GMNIA). Doubling the number of protection layers, from 12.5 mm thick to 25 mm thick, the fire resistance increases by an amount of 72% to 100% when the load level changes from 6% to 36%, with respect to load bearing at room temperature. | eng |
