Effects of the combined action of axial and transversal loads on the failure time of a wooden beam under fire

Highlights: ► A wooden beam submitted to fire and axial and transversal loads is considered. ► The failure time is found to increase with the intensity of the loads. ► Implication for safety consideration is indicated. -- Abstract: This paper presents the variations of the failure time of a wooden beam (Baillonella toxisperma also called Moabi) in fire subjected to the combined effect of axial and transversal loads. Using the recommendation of the structural Eurocodes that the failure can occur when the deflection attains 1/300 of the length of the beam or when the bending moment attains the resistant moment, the partial differential equation describing the beam dynamics is solved numerically and the failure time calculated. It is found that the failure time decreases when either the axial or transversal loads increases.
