Cross beam systems are widely used in construction. They are used in bridge construction, industrial, civil and hydraulic engineering. Flat reinforced concrete floors are the most common elements of various buildings and structures. The use of engineering software systems that take into account new methods and algorithms for calculating the stress-strain state and the bearing capacity of reinforced concrete beams and transverse systems is an actual area of work. In the work, the calculation of the precast-monolithic caisson floor of the trading floor with square caissons is performed. Prefabricated floor beams. Characteristics of the studied model are given in the article. The calculation was performed using a computer program that numerically implements the tasks of calculating reinforced concrete grillages based on a spatial calculation scheme taking into account physical nonlinearity. In the calculation, the software package takes into account the creep of concrete, the condition of supporting the caisson along the contour, the prestressing of the reinforcement of the beams of one of the directions. The rigidity of the floor beams in areas with cracks is determined according to building codes. The stiffness of the beams in areas without cracks is determined by a formula that takes into account the long-term creep of concrete. The results of computer studies of the caisson floor model are presented. Experimental data are considered. As a result of the calculation, it was found that the calculated deflections correspond to the experimental data.\u00a0 The effectiveness of the constructive solution of the horizontal and monochromatic caissons with the short front spacing ribs, which is free and tightened and three.
