STRUCTURAL ENGINEERING

• sophisticated static proof of the listed existing building (reinforced concrete skeleton construction of the year 1913 with approximately 30.000 m² gross external area) for a added ceiling force of an additional 1,5 kN/m² in almost all areas
• Proof of the transverse force load-carrying capacity of all cross girders due to the available lateral ties, the building was reinforced with punt iron, a special kind of reinforcement from USA where according to the today´s regulations is no effective transverse force reinforcement is present, but only insufficiently embodied bending upward
• Control and professional monitoring of ceiling pressure tests including the interpretation for the reduction of the rehabilitation complexity
• Development of a concept for the production of a sufficient shear bearing capacity through shot concrete rehabilitation
• Increase of the floor bearing capacity through dowel jointing blinding concrete (in areas)
• Production of the area stability of the entire building through execution of the installation shafts as braced cores, the solid appearing outer walls are only non-bearing façade
• Development of special measures for temporary construction security in the break off area
