    Abstract. The installation of masts on the braces to accommodate telecommunications equipment under the conditions of dense urban development is in most cases impossible or difficult. Latticed prismatic towers make significant changes in the architectural composition of the city. As an alternative, a new constructive solution of the towers, representing a central barrel with parallel pre-stressed tightening along the outer circumference, is proposed. The analysis and systematization of the existing experience in creating a constructive form of tower structures is performed. The work of the towers of the proposed constructive solution as supports for the location of the equipment of cellular operators is considered. To create a line of models for numerical experiments, the method of mathematical designing of experiments was used. For calculations, the finite element method was used for mathematical modeling with the help of software and computer complexes. The analysis of the changes in the stress-strain state of towers from influencing factors such as wind and payload, the diameter of the location of pre-stressed strings and their number was made. The rational dimensions of the tower and the ratio of its geometric parameters are determined by the criterion of minimum metal consumption of the towers. Preliminary recommendations for designing are offered. The directions of improving the constructive shape of the towers of this constructive solution are indicated.
    Key words: steel tower, new constructive solution, parallel tightenings, design scheme, design, comparative calculation.
