Effect of Thermal Loading on Various Types of Wood Beams

The paper deals with the experimental examination of flame burning on mass loss for the two types of wood beams - solid wood beam and glue laminated spruce wood timber (glulam). As for the glulam, the paper looks into the effect of the number of joints on wood burning. All samples have the same dimensions of 80 × 40 × 170 mm and moisture level of 15%. The samples are divided into three groups - glued laminated timber, glue and cross-laminated samples combined and solid wood samples. During the experiment, the samples are exposed to a flame for 10 min and the mass loss is recorded in 20 s intervals. Based on the values, the average mass loss is calculated for each set of samples. The conclusion consists of an evaluation and final findings.
