Исследования выполнены в вычислительном комплексе SCAD+ методом конечных элементов (МКЭ). В результате проведенного исследования получены, систематизированы и наглядно показаны зависимости прогиба и напряжений от варьирования шага поперечных ламелей перекрестно-клееной плиты, состоящей из 5 слоев. Выявлено, что при увеличении расстояний между ламелями в поперечных слоях увеличиваются прогибы и значительно возрастают нормальное напряжение вдоль пролёта. При этом, в среднем слое напряжение растет незначительно, что свидетельствует о том, что основную нагрузку при изгибе воспринимают верхние и нижние слои, работающие на сжатие и растяжение соответственно.</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>деревянные конструкции</kwd><kwd>CLT-панели</kwd><kwd>древесина</kwd><kwd>распределение напряжений</kwd><kwd>прогиб.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>wooden structures</kwd><kwd>CLT-panels</kwd><kwd>wood</kwd><kwd>stress distribution</kwd><kwd>thickness</kwd><kwd>deflection.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ашкенази Е.К.
