Strut-and-Tie Model Reinforced Concrete
The “Strut-and-Tie Model Reinforced Concrete” program generates strut-and-tie models for the design of reinforced concrete components. Right-angled structures with any number of re-entrant corners as well as recesses can be calculated. In the first version of the programme, the focus is on generating stiffness-optimised strut-and-tie models with a given component geometry and load.

Basis of analysis
The basis of the calculation is a topology optimisation algorithm based on the so-called ground structure method. This method consists in finding a maximally stiff frame with as few members as possible.
Verification/quality criteria
Verification of the following quality criteria in the determination process of the strut-and-tie model:
- Crossing compression struts – in this case the strut-and-tie model becomes invalid
- Verification of acute angles between compression and tension struts according to the strut-and-tie modelling theory by Schlaich/Schäfer
Design
In the current version, the design and the reinforcement layout are not available yet. All member forces with the resulting horizontal and vertical load components can be put out.
