    Abstract. Investigations by various authors, experience of domestic and foreign construction make it possible to assume that a bearing frame which includes bearing walls and flat precast-monolithic floors with hollow-core slabs will be technologically attractive and cost-effective for high-rise buildings. The test of a natural floor and its joints with bearing walls has been conducted. Loading test results and theoretical analysis show that this floor supported on bearing walls is designed according to current Russian normative documentation and have the bearing capacity and stiffness much higher than required. It is ensured by tight contacts between elements of the floor and with bearing walls as well as by the presence of internal connections. In the floor, due to tight contacts and internal connections, the structural integrity was provided. Each cell operates like a one-piece plate supported along the contour. Redistribution of forces between elements of the floor contributes to significant reduction in the value of forces in each hollow-core slab comparing with the scheme of free bearing. The test results of the floor deck, theoretical analysis and experience in the construction of 25-story building fully confirmed the high reliability and efficiency both of the floor structure and the bearing frame as a whole.
    Key words: flat floor deck, hollow-core slabs, bearing walls, plate, strength, stiffness.
