Experimental and numerical investigation of the response of GLT beams exposed to fire
Original language description
This paper presents a combined experimental and numerical investigation of the behavior of glued lam-inated timber beams when exposed to fire. The influence on the time variation of charring rates based onthe evolution of temperature profiles is examined for different fire scenarios and durations as well as dif-ferent beam’s cross-section sizes. Predictions of charring depths provided by numerical simulations ofheat transfer and simplified charring rate models are compared. In the absence of a mass transport rep-resentation, a Bayesian inference is introduced to identify the temperature-dependent material parame-ters for the conventional heat transfer model. A similar approach is adopted when adjusting the selectedparameters of the charring rate models to account for variations in actual fire scenarios, which potentiallydepart from standard fire exposure. When compared to experimental results, both approaches confirmedtheir predictive capabilities, particularly in the stage of initial design. Since presented in the framework ofBayesian statistics, they open the door to fully stochastic analysis with an emphasis on the load bearingcapacity of the studied beams
