Abstract
The study examines the effect of the transverse and longitudinal layers thickness of a three-layer CLT panel on the deformations and distribution of the resulting tensile and compressive normal stresses in the layers. Due to the current lack of a unified methodology for the calculation of multilayer materials with orthotropic properties in layers at present, we carried out the study with the SCAD+ computing complex using the finite element method. The studied model was a composite orthotropic plate. The authors obtained, systematized and clearly showed the dependences of the values of the maximum deflection and normal stresses on the thickness variation of transverse and longitudinal lamellae in a three-layer CLT panel under different boundary conditions. As a result of the study, we found that the greatest influence on the deflection and normal stresses along the span was caused by the longitudinal slab layers. The results provide a better insight into the relationship between deformability and stress distributions and the variation of transverse and longitudinal layer thicknesses. The obtained patterns can be used in the design of building structures using CLT panel.
