I am modeling a single span prestressed concrete I girder bridge as per as-built plans (using LARS v20.02.01.121)
everything is working fine except for the Service I Strand tension rating factor which is less than 1.0
can anyone explain what is controlling this check?

The Critical RF which is less than 1.0 is due to Prestressing Steel Tension Capacity for Permit Load:
The calculations are based on MBE A3 example and the factors affecting the RF is fr , fpe , fs (psc) and Fs Reinf.
