The analysis of the experimental and theoretical results of glued beams under oblique bending was conducted similarly to that for beams under direct bending. The displacement isofields of the beams at inclination angles of 10° and 25° along the Z-Z and Y-Y axes are shown in Figs. 5 and 6.

In the graphs comparing the results of experimental and theoretical studies under oblique bending, the average total deflection values of glued beams GLB-3 and GLB-4 at an inclination angle of 10° were used. A similar comparison was performed for beams GLB-5 and GLB-6 at an inclination angle of 25°. The graphs showing the dependence of deflections on bending moments for glued beams under oblique bending conditions are presented in Figs. 7 and 8.
