Stairs and elevator shafts are designed as monolithic reinforced concrete, made of class B25 concrete with class A400 and A240 reinforcement. Monolithic elevator shafts are stiffening diaphragms. The calculation of the supporting structures of the frame was carried out in the SCAD Office 11.3 software package, taking into account the joint work with the base. The required fire resistance of reinforced concrete load-bearing structures is provided by increased protective layers of concrete for working reinforcement. The foundation of the building in axes 1-17 / A-P is piled. Piles - bored with a diameter of 520 mm.
