As part of the renovation of the Černý Most Center, the ceiling load on the first floor was reinforced by replacing the supporting spiroll panels. The load-bearing structure consists of embedded beams and joists made of rectangular profiles, which reduces the structural height and eliminates buckling. Stabilizing bracing with a truss column ensures the rigidity of the structure, provides stability, and allows for efficient load transfer to the beams. The reduction in rigidity is compensated by diagonal stiffeners and shear stops, which ensure interaction with the adjacent structure.
