Abstract: This paper is based on the background offered by an extended research project aiming to analyze and develop a testing system for the mechanical behavior of some new configurations of bio-based composite materials (more specifically glued laminated timber) when subjected to high temperatures. The need for this type of materials is becoming more topical due to the attempt to replace the building materials whose production is energy-intensive (especially steel and concrete) with bio-renewable building materials (as, for example, wood) within the framework of the European “Green New Deal” policy to reduce greenhouse gas emissions, of which the construction industry is considerably responsible. Current engineering practice focuses on normal environmental temperatures, however radical behavior changes may occur during a fire. The subject of the present paper deals with the assessment of changes occurring in the mechanical parameters of massive wood products (more specifically glued laminated timber-glulam) due to temperature variation, especially close to pyrolysis temperature. The testing samples were prepared using current adhesive solutions and wood essences as in the case of the real-scale structural glulam elements. The heating gear was embedded in the glued midplane of the sample to apply different temperatures. Tests were performed in direct shearing equipment, where the glued section was fitted in the middle of the shear box. Changes in the mechanical behavior of wood at high raised temperatures are monitored but the focus is on the variation of the adhesive parameters during testing.
