Structural Analysis Program Issues
Structural Analysis Program Issues
(OP)
Hello,
I work for a precaster in AZ and we are making the switch from Salmon's BEAM program and our in-house program to Bentley's Presto. I have been testing Presto and comparing it to our other programs and the PCI/ACI codes. Unfortunately, for final losses Presto outputs roughly 13% higher tension in the bottom under full DL and LL.
Something else that Presto outputs that we surprised by is when it cracks under tension it displays -0 (negative zero). I thought ACI had equations for a reduced ultimate strength and for calculated the stresses in cracked sections of concrete.
We have a help ticket with Bentley, but I'm under a little pressure to figure this out sooner than later.
Thanks for your help in advance (This is my first post!),
Wyatt

RE: Structural Analysis Program Issues
So, most of what you are asking you can solve with a spreadsheet or worksheet able to study your section in compatibility of deformations; they are not so difficult to build, and also there are out there a number of them, myself's at Mathcad Collaboratory that unfortunately I don't think are available to the public as it was the case before PTC's Mathsoft purchase.
