The model shows a reinforced concrete building complex in Hamburg's HafenCity with an 18-story office high-rise, a 7-story office building, a 9-story residential building, and a two-story underground car park. The design considered the influences of multi-story construction and the requirements for vibration decoupling due to the U4 subway line. RFEM was used for the calculations. The client, grbv Ingenieure im Bauwesen GmbH & Co. KG, was responsible for the structural design of the building and excavation. The 3D model visualizes both the high-rise and residential areas.

The "Nonlinear Material Behavior" add-on includes the "Anistropic | Damage" material model for concrete structural components. This material model allows you to consider concrete damage for members, surfaces, and solids.
You can define an individual stress-strain diagram via a table, use the parametric input to generate the stress-strain diagram, or use the predefined parameters from the standards. Furthermore, it is possible to consider the tension stiffening effect.
For the reinforcement, both nonlinear material models "Isotropic | Plastic (Members)" and "Isotropic | Nonlinear Elastic (Members)" are available.
It is possible to consider the long-term effects due to creep and shrinkage using the "Static Analysis | Creep & Shrinkage (Linear)" analysis type that has been recently released. Creep is taken into account by stretching the stress-strain diagram of the concrete by the factor (1+phi), and shrinkage as the pre-strain of the concrete. More detailed time step analyses are possible using the "Time-Dependent Analysis (TDA)" add-on.

For concrete design, you can display the reinforcement results in tables separately by design situation.
How can I determine the sufficient total simulation time for an accurate transient wind analysis in RWIND?
