    Abstract. The article proposes a methodology for assessing the deformability of inter-slab joints in precast hollow-core slab floors in multi-story frame buildings. The experience of experimental studies of precast floors under horizontal load is analyzed. The calculation model is based on a plate-and-rod scheme, in which all joints and support contacts of slabs with beams are modeled by rod elements, the rigidity of which is determined based on the results of numerous experiments and the laws of solid mechanics. For various design solutions for connecting hollow-core slabs, specific recommendations are given for determining the rigidity characteristics of the elements of the calculation model. Using a specific example of testing a ceiling fragment made of multi-cavity ordinary and bonded slabs supported on prefabricated crossbars, which in turn rest on fragments of jammed columns, satisfactory convergence of the results of the theoretical determination of the movements of the slab or ceiling cell from a horizontal load with experimental data is shown.
    Keywords: multi-storey frame buildings, junctions of prefabricated floors, vertical stiffness elements, rod elements, hollow-core slabs, deformability of inter-slab joints
