Contact deformation behavior of elements of spherical support structures of different geometrical configuration was considered: with anti-friction layer located in the lower steel slab and with anti-friction layer applied to the spherical segment. Within the framework of the paper, numerical analysis of the effect of the anti-friction polymeric layer face angle of spherical support structures on the deformation behavior of the work as a whole and changes in the parameters of friction contact zones, in particular, was performed. On average, the maximum contact pressure level of the spherical support structure model with a layer located in the lower slab is 8.5 % lower, and the maximum level of normal-to-surface movements is more than 28% lower than that of the second model considered. The opening of the contact near the edge of the anti-friction layer approximately by 1% of the surface is observed in all considered variants of spherical support structures. Areas of contact detachment of the interface surfaces in the model with an anti-friction layer in the lower slab are observed at a face angle of 20 degrees or more. For the model with an anti-friction layer applied to the spherical segment, an opposite situation is observed, namely, the contact opening occurs at the face angles from 0 to 10 degrees. In general, with an increase in the face angle from 0 to 30 degrees, there is an increase in deformation parameters of the contact node and parameters of contact zones.
