An analytical method is presented for calculating stresses and strains inside wooden structures exposed to elevated temperature. The method combines stress analysis of elasticity with thermal analysis of heat transfer and property degradation models. Finite element methods were used for the analyses. Numerical results were generated for two different types of wooden structures made of Southern Pine. Stresses and deformations were calculated for the structures exposed to different environmental loading conditions. It was found that, based on the proposed analysis, the order of thermal and mechanical loading sequence had no effect on resulting stress distributions inside the wooden struc tures.
