Klestov O. Stress-strain state and bearing capacity of reinforced concrete slabs with steel framing

The object is reinforced concrete slab with steel framing; the purpose is research of stress-strain state and bearing capacity of reinforced concrete slabs with steel framing by experimental, analytical and numerical methods; the methods are experimental researches of stress-strain state and bearing capacity of reinforced concrete slabs with steel framing, methods of structural mechanics, strength of materials, resistance of reinforced concrete in analysis of stress-strain state of composite structures of steel and reinforced concrete, method of computer simulation of structures using software packages realizing finite element method; the novelty - the method of analytical calculation of reinforced concrete slabs with steel framing is designed, the influence of steel framing on stress-strain state and bearing capacity of reinforced concrete slabs; the stress-strain state of reinforced concrete slabs with steel framing by numerical methods considering physical nonlinearity of materials was analyzed; the technological and economic efficiency of introduced reinforced concrete slabs with steel framing consisting of composite structures of steel and reinforced concrete girderless floor compared regular reinforced concrete structures was estimated; the results - new composite structures of steel and reinforced concrete was designed; the stress-strain state of reinforced concrete slabs with steel framing on-loading was estimated; the methods of analytical and numerical calculations have been improved; the technological and economic efficiency of composite structures of steel and reinforced concrete girderless floor have been proved; the industry is building
