The design of solar systems on the surfaces of buildings is based on an integrated approach to modeling: the duration of irradiation, zones of effective irradiation, shading zones, and angles of incidence of sunlight on the surface. In this case, the

One way to increase the overall stiffness of a shell structure is to design shells with variable thickness. The effect of thickness change on the stability of flexible shallow panels has been little studied due to the complexity of solving such non-l
