The paper deals with the formation of hierarchic cable roofs and calculation principles. The structure is formed by negative Gauss bended type saddle shaped cable roofs, by suspending separate saddle roofs corners to a higher level cable structure created by high-strength carbon fiber cables. For these structures all prerogatives which are typical for a saddle shape cable roof can be applied however, with a better correlation between the covered volume and the area. The structure behavior is characterized by geometric nonlinearity. To reduce the complexity and the amount of calculation and to avoid calculation matrix convergence problem the method of substructuring is used. By using the available software, calculation of stress and displacements of complicated hierarchically subordinated structures can be made, and the effect of displacements of separate structural elements on the all the rest of them can be defined. It is suitable to use hierarchic cable structures for great span coverings, the areas without any snow or with insignificant snow load, as well as these structures may be used as completely or partially dismounted provisional coverings.
