Original language description
The paper is focused on a timber joint with an inserted steel plate under fire exposure. To investigate its behaviour, fire tests of bolted timber joints with inserted steel plate were designed and carried out. The results show a positive effect of inserted steel plate on timber burning rate caused by water accumulation in the timber element close to the steel plate and higher burning rate than predicted by the analytical model. A study which investigates the influence of various parameters on the heat transfer in the joint is based on finite element model in ANSYS. The results of model is validated on experimental results. The outputs of the analysis can be used for the joint design in order to increase fire resistance of the joint.
