Ram Concept: Capacity differences between two the same beams due to strip defined - not consider as PT vs consider as PT

If we are strictly talking about strength design capacity of beams per ACI 318-11 code, then it comes down to the differences in ACI section 10.2 for RC Beams and 18.7 for PT beams for flexure, and the difference between 11.2 for RC beams and 11.3 for PT beams for shear. In a nutshell the tendons are considered in the capacity of PT beams per ACI Section 18.7. For shear in PT beams we use equation 11-9 which causes differences.

These sections from the manual should help:

Section 18.7 Design Flexural Resistance (Prestressed) and Section 11.3 Shear Resistance of Beams (Prestressed)

Actually, I am using Eurocode 2, can You tell me which formula Ram Concept use to calculate those differences? I do not have ACI code to check it.

Thanks in Advance.

I'm less familiar with that code, but according to the Ram Concept manual, section 63.4.7 these are the code sections for beams:

It looks like TR-43 5.8.5 is making the difference in flexural capacity and TR-43 5.9 is affecting shear.
