    Abstract. To determine the economic efficiency of the use of monolithic reinforced concrete slabs when calculating the building for progressive collapse, three structural solutions of the slab were adopted: beam, beam ribbed, beam with beams in two directions. Calculations and selection of reinforcement in the ceilings during normal operation of the building as well as an additional calculation for progressive collapse were made. The difference in the reinforcement of overlaps when calculating only for normal operation and with an additional calculation for the progressive collapse is determined. The calculation of the material consumption of the floors, labor costs and the cost of their construction both at normal operation and with an additional calculation for progressive collapse is made. On the basis of the performed calculations the conclusions about the economic efficiency of the use of various structural variants of ceilings are made. Beam overlap with beams in two directions, combining the advantages and disadvantages of other options, has a better resistance to progressive collapse, herewith an increase in reinforcement in it after the calculation of the secondary state is minimal.
    Key words: progressive collapse, monolithic reinforced concrete floors, progressive economic efficiency of structural solutions, frame buildings.
