Abstract
The influence of the step of the transverse layers of five-layer slabs of cross-glued wood (CLT panels) on the deformation and distribution of the resulting normal and tangential stresses in the layers of the structure is considered. The research was carried out in the SCAD+ computing complex by the finite element method (FEM). As a result of the conducted research, the dependences of deflection and stresses on the variation of the pitch of the transverse lamellae of a cross-glued plate consisting of 5 layers are obtained, systematized and clearly shown. It is revealed that with increasing distances between lamellae in transverse layers, deflections increase and the normal stress along the span increases significantly. At the same time, the stress increases slightly in the middle layer, which indicates that the upper and lower layers, working for compression and stretching, respectively, perceive the main load during bending.
