One of the main directions of development of mobile communication systems, radio engineering and telecommunication systems is the improvement of the structural form of the bearing supports, which will solve a number of practical tasks: to increase the coverage area, to ensure higher rates of data transmission speed and to ensure stable operation in an increasing number of users. These circumstances justify the relevance of research in this direction. Aims of research. Optimization of design solutions using parallel puffs, ensuring the possibility of erection and safe operation during the entire service life, which ensures that the requirements for strength, stability and deformations for such structures are met with minimal material consumption. Methods. For calculations, finite element methods are used for mathematical modeling using software and computing systems. To create linear models for numerical experiments, the method of mathematical planning of experiments was used. Results. The work of the towers of the proposed constructive solution is considered as supports for the placement of equipment of cellular operators using the example of a 42-meter tower. The method of mathematical planning of experiments was used to create a model line for numerical experiments. To establish the basic characteristics of the stress-strain state of the structures of the supports, a number of models were created and calculated in software packages, the basis of which is the finite element method. A comparative analysis of the effort in the delays determined by analytical calculation and the finite element method is performed. The analysis of changes in the stress-strain state of the towers from the influence of influencing factors, such as wind and icy-wind loads, the angle of deflection on the lower tier of the tower. By the criterion of minimum metal consumption and manufacturability of the construction of towers, rational overall dimensions of the tower were determined. The options for constructing the main junctions of the elements of the tower are proposed.</p></abstract><trans-abstract xml:lang="ru"><p>Актуальность. Одним из основных направлений развития систем мобильной связи, радиотехнических и телекоммуникационных систем является совершенствование конструктивной формы несущих опор, что позволит решить ряд практических задач: увеличить зону покрытия, обеспечить более высокие показатели скорости передачи данных и стабильность работы в условиях растущего количества пользователей. Указанные обстоятельства обосновывают актуальность исследований в данном направлении. Цели. Задача исследования заключалась в оптимизации конструктивного решения башен с параллельными затяжками, обеспечивающего возможность возведения и безопасной эксплуатации на протяжении заданного срока службы путем выполнения требований по прочности, устойчивости и деформациям к таким сооружениям при минимальной материалоемкости. Методы. Для расчетов применялся метод конечных элементов для математического моделирования с использованием программно-вычислительных комплексов, а при создании линейки моделей для численных экспериментов - метод математического планирования экспериментов. Результаты. В статье рассмотрена работа башен предложенного конструктивного решения в качестве опор для размещения оборудования операторов сотовой связи на примере башни высотой 42 м. Для установления основных характеристик напряженно-деформированного состояния конструкций опор созданы и рассчитаны модели в программных комплексах, в основу работы которых заложен метод конечных элементов. Выполнен сравнительный анализ усилий в оттяжках, определенных аналитическим расчетом и методом конечных элементов, а также анализ изменения напряженно-деформированного состояния башен от воздействия влияющих факторов, таких как ветровая и гололедноветровая нагрузки, угол наклона оттяжек на нижнем ярусе башни. По критерию минимальной металлоемкости и технологичности возведения башен определены рациональные габаритные размеры башни. Предложены варианты конструирования основных узлов сопряжений элементов башни.</p></trans-abstract><kwd-group xml:lang="en"><kwd>design</kwd><kwd>metal structures</kwd><kwd>steel tower</kwd><kwd>new design solution</kwd><kwd>parallel tightening</kwd><kwd>design scheme</kwd><kwd>design</kwd><kwd>comparative calculation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>проектирование</kwd><kwd>металлические конструкции</kwd><kwd>стальная башня</kwd><kwd>новое конструктивное решение</kwd><kwd>параллельные затяжки</kwd><kwd>расчетная схема</kwd><kwd>конструирование</kwd><kwd>сравнительный расчет</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Golikov A.V., Sitnikov I.R.
