As part of the renovation of the Černý Most commercial and cultural center, the existing void was covered with steel truss girders. These are located in a module and connected to the reinforced concrete and steel structures, with a maximum girder span of 16 m. Additional trusses are used to support the new ceiling structure, with the upper chords made of HEB profiles and the lower chords made of square tubes. The ceiling is made of reinforced concrete ribbed slabs on trapezoidal sheet metal, which acts as permanent formwork. The main spatial rigidity is ensured by bracing against the existing structures.
