Nyzhnyk O. Girderless floor and joist floor of composite structures of steel and reinforced concrete

The aim of the work - creating, research, calculation and designing of new effective kinds of girderless and joist floors of composite structures of steel and reinforced concrete. The object - girderless and joist floors of composite structures of steel and reinforced concrete. The research technique - the comparing of experimental and theoretical, methods of theory of planning of experiment, methods of structural mechanics, strength of materials and reinforced concrete, method of computer simulation with using software packages. The novelty - for the first time the new effective kinds of composite structures of steel and reinforced concrete constructions of girderless and joist floors have been offered and produced, specifics of working under the load and specific forms of their destruction have been detected, the impact of different factors on deformability and carrying capacity of floors have been determined, the analytical methods of calculation of composite structures of steel and reinforced concrete have been offered, the numerical methods of calculation of offered floors have been developed further; results - recommendation of designing and construction of girderless floors of composite structures of steel and reinforced concrete have been developed, the economic benefit of introduction of new kinds of girderless and joist floors of composite structures of steel and reinforced concrete in practice of designing and construction have been got.
