Results of research of wooden beams with cracks located neutral axis: an experimental study

The results of experimental studies of glued wooden beams with through cracks along the neutral axis are presented. The distribution of tangential stresses along the height of beams in different cross-sections has been established. The distribution of normal stresses along the length of the studied beams was obtained. Diagrams of relative displacements of the edges of cracks in beams and their increments were constructed. The bearing capacity of glued wooden beams is established.
