How does Sofistik calculates the longitudinal reinforcement

Dear all

I’m trying to discover how SOFISTIK designs the reinforcement of a beam.
In the group ‘Design reinforced concrete’, I choose for the following tasks:

  • Design ULS (beams) - default settings
  • Design SLS (beams) - default settings

I have a rectangular cross-section.

I found that first in the report, SOFISTIK gives the required reinforcement for the different load cases and sections of the beam, which corresponds with my calculations.

Afterwards in the report, you can find the longitudinal reinforcement for the different design cases (ULS and SLS). These values are still no practical values, but they use the required values.
Except, if you predefine in the cross-section more reinforcement area than required.
Is there an option, the software designs the best reinforcement scheme for each case, without taking into account the predefined values of the cross-section?

Kind regards
Sharon

Hi,

Do you mean if you define reinforcement more than enough, if the program is able to tell you to reduce it? I think you can enter a reinforcement line and keep the amount much lower than expected and you will get definitely higher area than defined. That should solve it.
