Shekhorkina S. Rational design of low-rise floating dwelling houses

Subject of inquiry is structures of low-rise floating dwelling houses. Thesis objective is aimed at the development of science based positions of rational design of low-rise floating dwelling houses taking into account the specific service conditions and loads. Research methods - system analysis, methods of numerical modeling, methods of mathematical statistics and data processing, methods of variant design, methods of technical-economical assessment of dwelling houses designs, statics theory of the ship. Theoretical and practical results: method of low-rise floating dwelling houses structures rational design which enables the building area extension is developed; the construction of floating platform of reinforced concrete pontoon-modules which can be used as foundation for low-rise dwelling houses or pontoon bridge, mooring and other kind of floating structures was designed (Ukrainian patent for utility model № 83103). Novelty of the research - science based positions of technical parameters of low-rise floating dwelling houses calculation which consider the demands of Ship register of Ukraine and current building codes have been obtained , namely: method of technical parameters calculation of low-rise floating houses was developed and the peculiarities of loads and impacts on such houses were determined (received first); the construction of floating platform of reinforced concrete pontoon-modules for low-rise dwelling houses was designed (developed further); the data of stress-strain state of structural elements of floating dwelling houses taking into account the combined action of floating platform and superstructure were obtained (developed further); the experimental data of concrete durability in conditions of sulfate corrosion were obtained and the rational structural-technological parameters of floating platform which provide demanded durability along with minimal cost were proposed for different exploitation conditions (developed further); economic effect of the construction of low-rise floating dwelling houses was defined (received first). Implementation extent: the results of investigations were used in development of hothouse complex on pond-cooler of DTEK "Kryvoriz'ka TES" (the act of results implementation from Prydniprovskyy science centre dated 05.06.2013). Range of application: development of low-rise floating dwelling houses designs by engineering and construction companies, individual contractors.
