The model tower in Avondale Forest in Ireland represents a modern solution of a timber structure, where all the structural details have been precisely implemented. The project is being realized by WIEHAG GmbH from Altheim, Austria, and focuses on the characteristic elements of towers and masts. The application integrates detailed views that highlight the interplay between aesthetic form and technical execution of the timber structure. Innovative calculations and structural subtleties bring the model to life and provide in-depth insights into the design process. The realistic representation underscores the high standards of material efficiency and sustainability in timber structures.

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 using the factor (1+phi), and shrinkage is taken into account as the pre-strain of the concrete. More detailed time step analyses are possible using the "Time-Dependent Analysis (TDA)" add-on.

In the Concrete Design add-on, you can determine the required longitudinal reinforcement for the direct crack width analysis (w k).

For the design of reinforced concrete members, there is the option to automatically determine the number or diameter of rebars.

For concrete design, you can display the reinforcement results in tables separately by design situation.
Why is the effective depth different with the effective depth used in shear checks?
How can I check the determination of the required reinforcement?
