Intelligent Quarters Hamburg, Germany
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.

Model Data of the 18-Story High-Rise Office Building
The property has a total surface area of 97,952 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 U4 subway line.
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 U4 subway line. 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.

This article compares the design with the one in the following article: Design of Concrete Columns Subjected to Axial Compression with RF-CONCRETE Members. It is therefore about taking exactly the same theoretical application carried out in RF-CONCRETE Members and reproducing it in RF-CONCRETE Columns. Thus, the objective is to compare the different input parameters and the results obtained by the two add-on modules for the design of column-like concrete members.
The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows softening of the material, which can be different in the local x- and y-direction of a surface. The material model is suitable for (unreinforced) masonry walls with in-plane loads.
- In RF‑CONCRETE Surfaces, I obtain a high amount of reinforcement in relation to a lever arm that is almost zero. How is such a small lever arm of internal forces created?
- What is the meaning of the superposition according to the CQC rule in a dynamic analysis??
- When converting from the manual definition of reinforcement areas to the automatic arrangement of reinforcement according to Window 1.4, the result of the deformation calculation differs, although the basic reinforcement has not been modified. What is the reason for this change?
- Does the program check the lap length of the vertical stirrups of a block foundation with smooth bucket sides?
- Why do I get a discontinuous area in the distribution of internal forces? In the area of the supported line, the shear force VEd shows a jump, which does not seems to be plausible.
- Is there a possibility in RFEM to define a global polar grid whose origin lies, for example, in the global zero point and which applies to several surfaces?
- When comparing RF‑CONCRETE Columns with another design software, I get different results. How to explain the differences?
- Is it possible to perform design without an additional reinforcement in RF‑CONCRETE Surfaces?
- My aim is to mesh a circular hole plate in a mapped way. Is such a meshing possible in RFEM?
I have installed Halfen HDB 13.60 on my PC. The version does not seem to be compatible with RF-PUNCH Pro anymore. The interface does not work. I am using version 5.26.02 of RFEM.
