Abstract
The new forms of building structures are widely used for modern social buildings, exhibi- tion pavilions, sport and industrial erections. The possibility to create new forms of thin space shell structures on the base of normal cyclic surfaces is considering in the paper. The thin- walled shells formed by the system of the circles as well as by the system of right lines are the mostly comfortable for the erection on the building sites or for formation of the details of the structures. The normal cyclic surfaces are allowed to construct many different forms of the space structures. It is possible to create new space structures on the base of cyclic surface with combination of cylindrical or other surfaces.
