The advanced calculation methods for wood structural elements in fire situations proposed by EN1995-1-2 provide reduction factors of wood strength according to the temperature. The values of these reduction factors given for compression and tension strength are relatively well documented. However, the reduction factors of wood shear strength with temperature were not studied. This study concerns experimental investigations conducted to characterize the evolution with temperature of the shear strength of wood. The tests are realized using a specific original specimen specially developed for this study. The experimental results allow evaluating the values given in EN1995-1-2.
