Petrushevskaya A. The stress-strain state of steel-concrete beamless slabs

Subject - the deformation and fracture of steel-concrete beamless slabs under short-term loading, the goal - the development of methods to assess the stress-strain state and determine the carrying capacity of steel-concrete square slabs as part girderless overlap with different support conditions on the basis of experimental and theoretical research methods - analytical, numerical and experimental; novelty - a mathematical model and method of numerical evaluation of the stress-strain state of steel-concrete slabs with different support conditions at the corners in force action, according to the experimentally obtained load-deformation load-deflection of the square in terms of steel-concrete floor slabs with different pitches anchor stops (with spacing of 100 mm and 50 mm along the perpendicular from the center of the plate to the middle of the edge and from the center to the corners along the bisectors of angles) and with different support conditions - swivel bearing on the corners and fixed at the corners and obtain experimental data on the load-bearing capacity, deformation, stress, domestic efforts in the investigated steel-concrete slab structures under static load applied; proposed theoretical model for the calculation of reinforced concrete slab finite element method, the results - the stress-strain state and the limit of beamless steel-concrete floor slabs, the sphere of use - design, construction, reconstruction and strengthening of buildings and industrial buildings.
