solid wood, bearing capacity, oblique bending, bending stiffness


The article is devoted to studying the features of the work of solid pine wood beams under direct and oblique bending. The study of oblique bending is represented by different angles of inclination. The destructive load of the beams under such conditions and the deformation parameters of bending elements were determined. Experimental results were compared with theoretical ones obtained as a result of calculations in the "LIRA" software complex. Study and analysis of calculations for different types of stiffnesses (with orthotropy, without orthotropy, and with the complete wood deformation diagram) using the software package was carried out. The optimal type of stiffnesses used in the "LIRA" software complex was determined based on the graphs for beam deformation. The results of experimental and theoretical studies can be used to design roof structure elements.
