Due to its properties, wood is used in engineering structures. Natural wood is often subjected to modifications aimed at, among other things, improving its aesthetic and technological properties.Thermal modification of wood allows for the improvement of these properties. Structures containing such materials, like most others, are exposed to the risk of fire. In the case of most construction materials, the impact of temperatures under fire conditions affects their degradation, which manifests as a loss of strength. The aim of the research presented in the article was a comparative assessment of the impact of fire environment temperatures on the strength of spruce wood subjected to and not subjected to thermal modification. Wood and wood-based composites are increasingly used in engineering structures. Wood is a non-homogeneous cellular composite, a composition of cellulose, hemicellulose, lignin, and other less significant components [1]. (…)
