Hi,
I am designing a bridge with draped strands in a prestressed concrete beam.
Typically the owner likes to have the bottom strands to 0.75, and they like to have 4 strands in the top stressed to 0.17.
When I add in the top row, the default is 0.75. However, when I change the pull percent to 0.17, the final tension at midspan remains identical to what it was before.
Has anyone else ran into this issue?
