Actions, Design Situations
The actions according to DIN 1055-100 are simply mapped to the load cases by the user. The program then automatically creates the decisive design values for the ultimate limit state and serviceability limit state while considering the safety factors and combination coefficients. For each combination different design situations can be defined for the construction and end states. When conducting the check, the extreme values deriving from all combinations and situations applies. Optionally, the checks can be carried out for all possible combinations of internal forces.
Ultimate Limit State Checks
- Minimum reinforcement for securing ductile behavior of the element
- Bending with or without longitudinal force or longitudinal force only
- Lateral force under consideration of the minimum level of reinforcement
- Pure torsion and torsion with lateral force
- Checks against punching shear
- Checks against fatigue for concrete, bending, lateral force and torsion reinforcement as well as for tendons
Checks at the Serviceability Limit State
- Limiting the concrete compressive stresses
- Limiting the reinforcing steel stresses
- Limiting the prestressing steel stresses
- Minimum reinforcement for the limit of the crack width
- Limiting the crack width via direct calculation
- Check of decompression
- Limiting deformations

Ultimate Limit State
The dimensioning of the reinforcement is performed separately on a per checks basis for the modeled design situations. This is determined individually for each combination of internal forces. The final outcome is a result of the extreme value derived from all calculated reinforcements. In the check against fatigue, the reinforcement that was previously determined is, if necessary, increased iteratively until the required stress range is met.
Serviceability
If required, the checks are carried out in state II under consideration of the calculated maximum reinforcement. In order to attain the required crack width, the minimum reinforcement is increased, if necessary.

Results
The calculated reinforcement can be output graphically (contours, color gradient, section or numerically) or in table form. This can be selected either for individual checks or for the entire reinforcement. The checks are documented in a detailed log. |
