Geometric studies and the calculation of thin shell conduits of non-canonical form

After 1965, the construction boom of large-span shell conduits begins to subside, i.e. the era of the “golden age of thin shell conduits” (1922-1965) ended. Only functionally necessary shell conduits were built, for example, tower coolers, or shell conduits that are built in addition to the main structure. However, after 2000, after the appearance of new building materials, new forms of shell conduits and improved methods for their numerical calculation, interest in this type of structure is renewed again. The goal of the project is to show the advantages of spatial thin-walled large-span structures compared to traditional ones and to attract interest to them from young architects and engineers. The objectives of the project are to expand the range of used forms of median surfaces and to develop improved methods for analytical, semi-analytical and numerical calculations of shell conduits of non-canonical forms. For the first time, more than 200 geometrical shapes with certain advantages over existing ones have been proposed for practical implementation. For each form, parametric, explicit, or vector equations are obtained, and all parameters of internal and external geometry are calculated. The classification of umbrella surfaces on the surface of the umbrella type and umbrellas surfaces themselves was carried out. Parametric equations of 19 umbrella-type surfaces are derived. These equations are obtained for the first time; no other analogues have been found in the literature. The analytical method for calculating the strength of direct helicoids has been reworked and prepared for the compilation of a computer program; a method has been proposed for calculating involute helicoids using Bernoulli numbers. A software package has been developed for calculating thin-walled spatial structures of complex shapes, taking into account all the geometric characteristics of the surface. The complex includes a library of curves and surfaces, on the basis of which structural forms of shell conduits are formed. The scope of results, examples of application. Koons’s modified surfaces will expand the possibilities of creating new diverse architectural forms in the construction of public, cultural, entertainment and sports facilities, and they can also be used in engineering in the design of complex products. One of the Koons’s surfaces was demonstrated at the All-Russian Exhibition Center, Moscow.

Energy self-supply of buildings and structures

Goals and objectives of the project - optimization of energy consumption, the use of new generation systems (not traditional schemes), especially combined systems: hydro, helio, wind power plant (WPP) and other types of generations for energy self-supply of cities and villages, in order to make them partially independent of centralized energy sources. In Moscow, as part of an experiment, construction of 16 energy-saving houses is planned. According to the government of the capital, the corresponding draft resolution was prepared by the Department of Urban Construction of the capital, not only residential buildings but also a public building was included in the list of addresses of the experimental design objects "Energy-saving housing in Moscow for 2010-2014 and for the period up to 2020".
