Overlap length of reinforcing bar

[andrea_pontiggia]

Where can I find the references that uses robots to calculate the overlap length of reinforcing bar with EC2?

thanks

Initially it calculated with formula 8.10 assuming:

alfa1   = 1.0,

alfa2   = 1.0,

alfa3   = 1.0,

alfa4   = 1.0,

alfa5   = 1.0,

alfa6   = 1.0

In formula 8.3 it is assumed that SigmaSd = fyd

After generation of reinforcement the verification of beam capacity is launched and at this stage Robot uses formula 8.4 calculating lb,rqd as from formula 8.3 assuming SigmaSd = Areq/Aprov *fyd so that the final overlapping length can be shorter than originally assumed (the final one is the one you can 'see').
