Studies conducted by the author in this thesis, it possible to formulate the main conclusions, recommendations and proposals for architectural design of high-rise office buildings, located on the territory of Iran. In this study, a high-rise office building in Iran accepted the building height from 12 to 60 floors (from 42 to 210 m), the decision in a unified architectural concept and provides for the creation of a favorable environment for the functioning of offices (including offices for the administrative apparatus) state and non-state (public) economic and other organizations and institutions. Analysis of theoretical studies, practice design, construction and operating experience of high-rise office buildings allowed: the prospects of further development of high-rise construction, including high-rise office buildings in the territory of Iran; define criteria for assessing the height of the building; form a classification of tall buildings (the number of storeys, the functional purpose); identify the basic requirements for the design of high-rise office buildings in Iran; to formulate the design of high-rise office buildings as the specific tasks of the system. The paper studied in detail the formation of the traditional practice of high-rise buildings and structures of Iran and Iranian analyzed modern high-rise office buildings. The analysis of the construction of high-rise office buildings in the territory of Ukraine, studied the most interesting high-rise administrative buildings. Compiled chart the growth and rise of high-rise office buildings in Iran and Ukraine. Thanks to the analysis of the world of design and construction of new high-rise office buildings, as well as the study of the results of experimental and competitive design in the world specialized competitions (US, UK, Japan, China, Germany, France, India, Russia) have been identified the world's major design trends of high-rise buildings. The paper reviewed the high-rise office buildings in the territory of Iran and Ukraine, as well as their compliance with the world trends in this aspect. The main factors that affect the design and construction of high-rise office buildings in Iran: external (urban planning, natural-climatic, ecological, social and environmental) and internal (functional-planning, design, engineering, architectural and artistic). Based on the analysis of Iranian and foreign experience in the design of high-rise office buildings, the work identified the main features of formation of architectural planning and design-technical structure of this type of buildings that include: special fire requirements; seismic, and structural engineering calculations; specific method of construction, strict control of construction, a system for monitoring high-altitude construction; special processing methods, special technical conditions; in the central part of the city there is the complexity of the connection to utilities, etc. A hierarchical diagram of a possible structure of a functional high-rise office buildings Iran, which includes the main functional groups, minor functional-forming constituents, group support facilities. Place your comparative analysis and determine the conditions functionally-forming components in the structure of the location of high-rise office buildings in Iran. Formed types of accommodation major functional-forming components in the structure of the high-rise building, developed schemes architectural design of high-rise office buildings in Iran. Formed principles of architectural design of high-rise office buildings in Iran: purposeful multifunctionality, architectural and artistic individuality, environmental and regional continuity. On the basis of the above principles have been identified to improve the rational methods of space-planning decisions of high-rise office buildings in Iran: the principle of appropriate functionality of poly (useful balance and the total area ratio of the functional-forming components, the distribution of communication flows); the principle of architectural and artistic individuality (individualization of volume-spatial and planning decisions); ecological principle (sun protection, temperature reduction, landscaping, planning techniques); the principle of regional continuity (quince, domed cover with svetoaeratsionnymi lanterns, punching, atrium with fountains, interior and exterior landscaping, as well as the accumulation and use of rain water, cooling with ice generation at night). The optimal architectural design and engineering systems for the design of high-rise office buildings, located on the territory of Iran on the example of the nine largest cities in Iran: Tehran (the capital), Mashhad, Karaj, Isfahan, Ahwaz, Tabriz, Shiraz, Qom and Kermanshah. recommendations provided by the study are based on the study of natural and climatic features of the five major climate-territorial zones of Iran and primarily aimed at efficient provision of architectural and structural and engineering reliability of high-rise office buildings and Iran are connected with the use of seismic protection, damping devices, the company aerodynamic three-dimensional shaped high-rise administrative building.
