I"m doing my first PT beam designs since the creation of Class T, and the increased limits on allowable tension. In going through the example in the ADAPT manual, they set the beam limits to 9 /f'c. I was going to use the full 12 /f'c, but now I'm wondering. Is there some reason to hold the...
Adapt sells some typical post-tensioning details on their website.
Has anyone purchased these and can offer an opinion as to their quality/usefulness? It's a little hard to discern what exactly will be in the package, as they don't offer much info or any samples.
I'm checking sealed wind load calcs from an awning manufacturer. When I calculated the loads in designing my building, I treated the canopy as a roof overhang under components and cladding. The engineer who did these calcs is treating it as...well, honestly, I can't tell. He seems to be only...
