When converting from the manual definition of reinforcement areas to the automatic arrangement of reinforcement according to Window 1.4, the result of the deformation calculation differs, although the basic reinforcement has not been modified. What is the reason for this change?


When using the automatic arrangement of the reinforcement, make sure that the additional reinforcement is applied, if necessary, for the serviceability limit state designs in addition to the basic reinforcement. The default setting in the add-on module is selected in such a way that the required reinforcement from the ultimate limit state is also applied for the SLS.

You can select the reinforcement that is applied for the SLS in "Additional Reinforcement for Serviceability State Design." The Info button explains the individual options (Figure 02).

The reinforcement applied to the designs can be followed by using the "Selected Reinforcement for SLS Check" function (Figure 03).
