The article is devoted to the development of prefabricated, frame frame-plate systems for housing construction in Ukraine. As a result of the preliminary analysis of frame systems, shortcomings were identified in both industrial prefabricated housing construction and monolithic and frame - this is a narrow gap between transverse load-bearing walls or pylons, which does not allow for reconstruction, design with planning options.In wartime, under the influence of explosive shells, as well as in difficult engineering and geological conditions and seismic areas, insufficient stability of structures is revealed, brittle destruction of nodal connections of floor slabs with columns occurs. Therefore, the "RAPL" system was developed for housing construction for ordinary and difficult conditions, which ensures the strength and stability of load-bearing structures, is economical, allows free and diverse use of the area of apartments and is suitable for the prospective development of housing construction, taking into account the possibilities of reconstruction of the building. The “RAPL” system is suitable for use in difficult operating conditions, it is the safest structural and frame system of the frame type with loop joints between columns and crossbars. Loop joints are the most important part of the frame frame design, which do not require welding. The “RAPL” system uses pre-stressed reinforcement in the frames with anchoring to the outer columns, which greatly improves the operation of structures, especially in seismic zones and during shell explosions. Such an architectural and structural system provides flexibility in architectural and planning solutions.
