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. |
