ABSTRACT
This paper demonstrates an approach to analyzing the strength and stability of cylindrical shell panels, which are used in construction as coatings and overlaps of buildings and structures. The ANSYS Mechanical APDL 19.2 software package is used for calculations. In the first two calculation models, the shell structures were fixed on two longitudinal straight sides with a fixed hinge, and on the other two sides with a curvature, they had a free edge. In the third considered variant of the shell design model, the structure was fixed pivotally-immobile along the entire contour. Concentrated force and evenly distributed load were considered as load variants. The calculations took into account the effect of the shell structure’s own weight. For all the considered variants of structures, graphs of the dependence of normal displacements on the load were obtained, the values were calculated taking into account geometric nonlinearity. The values of critical loads of stability loss were obtained for the variants of structures with evenly distributed load, while the other structures did not lose stability. Stress intensity distribution fields are obtained.
