The paper contains the methods of modeling the stress-strain state of the power industrial floor of the warehouse complex intended for storing products on multi-level racks, taking into account the operation of loading and unloading equipment in free space. Have been developed the finite-element model of stress-strain state of the floor under the action of a complex of dead and leave loads on the example of a real warehouse complex, taking into account the design soil conditions, the location of the foundation elements and the features of the installation of racking systems. Have been checked the design reinforcement, selected based on the results of classical calculations taking into account the equivalent pressure on the floor, using the deformation method for reinforced concrete structures. Have been found that the design reinforcement of the floor slab does not satisfy the strength conditions of the bearing floor under the action of concentrated influences from racking columns. Have been found a rational method of reinforcement and the optimal thickness of the bearing floor by sorting out the constructive options. Have been developed structure recommendations for mandatory cutting of seams on the floor in the area adjacent to the building's bearing columns. Have been recommended to reduce the size of the floor boards by cutting additional deformation joints to reduce the intensity of reinforcement. The rational size of the floor board should not exceed 20 × 20 m. Have been proved that the replacement of the actual concentrated influences from the columns of the racks by equivalent uniformly distributed pressures does not adequately reflect the performance of the floor structure and leads to false under-reinforcements of the bearing plate and, as a result, insufficient strength of the floor structures.
