CooperDBM,
I wasn't talking about calculating the ultimate capacity of the section, I was talking about determining the ultimate design moment that is to be checked against the ultimate capacity of the section. I actually have written a spreadsheet that iteritavely calculates the final strains...
Rowingengineer,
I reread my original post and dont blame you for being confused, I didn't really translate my thoughts into words very well.
Basically what I am suggesting is that the PT force is physically there and causes a hogging moment in the beam/slab. As such I dont understand why...
Hi guys,
I have a question regarding the load combinations used for determining ultimate bending moments in prestressed concrete. For arguments sake, just assume a rectangular beam carrying a uniform distributed load, with a parabolic PT cable that is stressed to balance out the deadload. In...
