Sir, I had capsulized my queries about your spreadsheet. Please help me to understand it very well because I'm not well knowledgeable in allowable stress design. I'm using Strength Design since I practice Civil Engineering. The following are my questions:
1. What is PS,HS,PI and DH stand for?.
2. Is there a general rule to estimate fci' at transfer, fci at transfer and fc at service given fc'?
3. How to determine the maximum allowable prestressing force (in kN) so that the prestressing steel will not break? Is this the same with the breaking strength on ASTM Standard?
4. How can we know if the section can adequately support the given bending moment (if there is)???. Is it by performing interaction diagram like in R.C.???
I'm using ACI and AASHTO as reference code.
Regards
