The main architectural landmark of the city of Nalchik, the capital of the Kabardino-Balkarian Republic, is the building of the Sosruko complex, distinguished by its unusual architecture and built in the 70s of the 20th century. The authors of the article turned to the symbol of the city because it is 55 years old and is a unique architectural ensemble. Sosruko is a wonderful monument of brutalist architecture that is visible from every corner of the city. This is evidenced by well-deserved awards and prizes for the originality of the design. Thanks to such buildings, which influence the image of the city, the architecture of the native land will not be the same and faceless. In our time, talented builders and architects should raise issues of preserving architectural heritage, and also remember the best works of architects who have made an invaluable contribution to the development of the construction industry of the Republic of Kabardino-Balkaria.

The experience of using blast furnace slag as an artificial foundation of the building foundation is considered. In the process of construction and installation works, the displacement of the columnar foundations was revealed due to changes in the initial properties of the blast-furnace slag. The chemical composition of the slag belonged to the group of inert materials. In fact, after layer-by-layer compaction, the process of disintegration of its initial properties began. The analysis of the conducted studies showed that in the regulatory and scientific literature there are no unambiguous recommendations on the use of this material as the base of buildings and structures. The recommendations that are available relate exclusively to its use in road foundations. From experience it follows: the use of slag in construction is possible, subject to confirmation of its compliance with specific construction conditions.

The article analyzes the calculation of the punching shear slab structures according to the recommendations of SNiP 2.03.01-84*concrete and reinforced Concrete structures. It is shown that the existing method of calculation gives overestimated the bearing capacity of floor slabs in bezrigelny frame systems. In order to establish the bearing capacity corresponding to the constructive decision is expected by calculation to determine the angle of the pyramid pushing.
