Model Data of the 18-Story High-Rise Office Building

In the center of HafenCity Hamburg, a new building complex with an 18-story high-rise office building, a seven-story office building, a nine-story residential building and a two-story underground parking garage was constructed.

The property has a total surface area of 97952 ft² and is located on exposed terrain near a river. For the structural design, influences from the multi-story construction were considered. In addition, a vibration analysis was performed as the building complex is located above the subway line U4.

The Dlubal customer grbv Ingenieure carried out the building structural planning as well as the object and structural planning of the construction area. The engineers of grbv utilized RFEM for the analysis and design.


The 18-story high-rise office building included a reinforced concrete supporting structure. The loads are transferred to the ground level through the columns and two internal cores, which are also used for building stabilization. The reinforced concrete floors are floating point-supported slabs without supporting beams. The building was designed as a complete 3D finite element model in RFEM and validated with comparative calculations.

The residential building is designed as a compartmentalized construction with linear supported flat slabs. Above the ground floor, long-span wall-like beams were designed to allow columns on the ground floor.

The unique design feature for this building was the positioning above the subway line 4. Since this is a residential building, it was necessary to provide dynamic damping to counteract the subway vibrations. This was done with an elastic decoupling between the ground floor and the additional upper floors with steel spring damper elements. After this design completion, vibration measurements were taken which met the client’s complete building requirements.
