The Republic of Moldova is characteristic for active seismic phenomena and there is always a direct danger of strong earthquakes. The building stock of the country has a complex character, this aspect is manifested in the municipality of Chisinau, where we have different buildings in terms of materials used, structural systems and height regime. New trends in construction are focused on buildings with a load-bearing frame structural system and a frame with a flat slab structure. The usual design practice is characteristic for the implementation of beam-column systems, where the plates are supported by the beams and the beams are supported by the columns. Nowadays, for the residential buildings design, a more elegant and ergonomic floor system is used - the flat slab system. Therefore, the slabs are subjected to increased loads, which requires special attention in the design and implementation of these types of structures.
