The actions according to EN 1991-2 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 value deriving from all combinations and situations applies.
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 result is derived from the extreme value of all calculated reinforcements.
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.
The following table demonstrates how the situations are used in the various checks. The numbers refer to the chapters of the standards.
|Situation||Load-Bearing Capacity||EN 1992-1-1||EN 1992-2|
|Permanent & temp.|
|Situation||Serviceability||EN 1992-1-1||EN 1992-2|
|Concrete compressive stresses|
Reinforcing steel stresses
Concrete compressive stresses
|Frequent||Decompression, class XC2-XS3|
Crack width, prestressing with bond
|Quasi-permanent||Concrete compressive stresses|
Crack width, reinforced concrete & prestressing without bond
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.
