New effective designs of steel towers are represented in article. The main advantages consist in light-weighty, durability, profitability, reliability, external esthetics and longevity. Applied modern types of sections: carobject, bent, profiled, perforated. Proposes the use of new types of the shape of farms and types of arch bars. Presents design features of an integrated application according to the needs of the customer, both industrial and civil. Rationally uses the space of the building. Noted some issues of manufacturing arches and installation of supporting structures. We have examined several structural and coating depending on the purpose of the facility. Attention is paid to the reduction of metal consumption and improve the environmental properties of the building. The General scheme of the location of structures and corresponding cross-sections. Discusses some of the design features of this design. The article is devoted to peculiarities of design solutions of towers, search for new metal resource economical designs and their operating conditions. The present work deals with the study of the behavior of a design, means of stabilization, determination of rational dimensions. Previously performed numerical and experimental studies of metallic thin-walled beams has allowed to establish the need for the development of constructions as a whole and its individual lattice elements. In the conditions of modernity in the aggravation of the problems of energy saving and resource saving become topical issues of minimizing the weight of structures, saving labor costs and reducing construction time. The results of these developments allow to increase the efficiency of metal construction with the use of effective elements, taking into account modern requirements to their design for wide introduction into practice while under the current system of normative documents. On the basis of the research developed principles of rational design of steel towers. Taking into account existing recommendations for optimization of the new approaches to the field of optimal design of farm structures and types of lattices in an arched construction. The article revealed that one of the ways to improve the efficiency and economy of steel building structures is the use of new progressive technologies, the widespread use of new economical sections of rolled products and creating new, more efficient designs using these profiles to create traditional constructive forms of new content, and make them simple and economical. Formulated the problem of development, improvement and optimization of structures in the construction industry subject to constant scientific and technical progress. Priority has always been to increase the efficiency of the designs by reducing metal consumption, complexity of manufacturing and installation. Simultaneously, the urgent task is to improve the reliability of building structures, by improving methods of their calculation and design. The work solves the problem of increasing the effective use of the metal in the rod structures, which is expressed in application optimal form elements depending on work structures with increasing bearing capacity and reducing the material consumption of the structure.
