Presented method and results of experimental research of deflection of single-layer and two-layer slabs influenced by short-term lateral load. Proposed method of calculation based on the limit equilibrium method, calculation of slab deflections values by LIRA-CAD bundled software. The comparison of experimental and theoretical results of the calculation of deflections slabs.
Layered constructions are increasingly applied in building recently. When appropriate composition of separate layers is selected, multi-layer constructions with perfect construction properties may be created . Layers are mostly composed of heavy concrete and effective steel fiber concrete. Such constructive decisions have a widespread use in road and airfield pavements, logistics areas, heavy-weight industrial floors, etc. [13, 15, 16]. Among the most promising trends of reasonable usage of steel fiber concrete is its application in composite structures, as a rule, in combination with concrete or ferroconcrete, with distinct partition of functions of every material. In particular, the steel fiber concrete that is rather thriftily applied along the construction outline, in a thin layer, provides high crack resistance of constructions, as well as well as its high durability due to high indices of tensile strength, frost resistance, corrosion resistance, and high rates of other types of resistance of the steel fiber concrete . At the same time, this solution provides necessary preconditions for significant reduction of strength and value of the primary concrete and reduction of the number of reinforcement rod. Thus, there are preconditions for obtaining high indices created while their cost drops.
