Bending characteristics of glued laminated timber depending on the alternating effects of freezing and heating

Popis výsledku v původním jazyce

This study investigates the effect of cyclic temperature variation on the bending properties of glued laminated timber made from combinations of wood species. One hundred sixty timber beams were created from three species, Norway spruce (Picea abies (L.) H. Karst.), Black alder (Alnus glutinosa (L.) Gaertn.), and European beech (Fagus sylvatica L.), which were chosen to represent hardwood and softwood species. Beams were glued together using one-component polyurethane (1C PUR) adhesive according to a combination key, with the verification series consisting of beams glued together from a single species. The beams were split into four groups, with three of them undergoing temperature cycling (-25 C and + 60 C) and the fourth serving as a reference. The bending characteristics, namely modulus (MOE) of elasticity and bending strength (MOR), were investigated. As a result, the cycling of our chosen temperatures does not affect the density change in the beams. The modulus of elasticity (MOE) was significan
