    Abstract. The issues of the use of reinforced concrete structures of formless molding are considered. These efficient and economical designs are widely used in low-rise construction. At the same time, the use of slabs of formless molding in the construction of a prefabricated frame of multi-storey buildings was limited by their design features. It is shown that the most effective use of such slabs is in precast-monolithic frame systems, where the advantages of precast and monolithic reinforced concrete are combined. To expand the possibilities of their use in multi-storey construction, research has been conducted in two directions - improving the technology of formless molding and developing a new structural system of a prefabricated monolithic frame. Advanced designs of formless molding have been introduced into production, in which the device of cutouts, dowels, loop outlets is provided, indirect mesh reinforcement has been added. An interspecific structural system has been developed, which combines the advantages of the technology of formless molding and the possibilities of the most technologically advanced ways of combining these elements into a single system without welding.
    Keywords: formless molding, reinforced concrete structures, prefabricated monolithic frame, interspecific frame system, multi-storey buildings
