Abstract
In this paper, the verification of the mathematical model previously proposed by the author for studying the stress-strain state of multilayer cylindrical panels from CLT is carried out. For this purpose, the calculation results of the author's model of three shells of different geometry made of a different number of layers are compared with the calculation results of such structures obtained in PC «Lira-SAD».Structures fixed along the contour in a hinged and rigid manner were subjected to the action of a small evenly distributed transverse load, with the greatest possible panel deflections of 4 mm. The comparison of the deformed state was carried out by the biggest deflection and the deflection in the center of the shells, as well as by the shape of the deformed state of the structures. At the same time, there was studied the influence of the number of functions in the expansion in the Ritz method on the accuracy of the proposed mathematical model. It is shown that with 16 or more terms in the expansion, the deflection calculation error in comparison with the Lira-SAPR PC does not exceed 10%.
