I agree. The decouple moment in the STM model would pretty much tell you that you need tension/tie reinforcement equal to the load multiplied by the cantilever length and that would continue over the supporting column into the backspan.
I think it is more of looking at the end anchorage, like...
RISA does seem to know its cantilevered. In the "Additional Properties" when clicking on the member, it says "Start Support Cantilever".
I am only talking inches, not feet. I agree with your thought process though.
Thanks for the responses. After I posted this, I kind of came to a similar conclusion. 2h seems like the right approach because that fits within the 9.9.1.1 b criteria of having a load within 2h of the support.
For my project this has come up on, I have the ability to move my cantilever...
ACI 318 defines a deep beam as:
9.9.1.1 Deep beams are members that are loaded on one face and supported on the opposite face such that strut-like compression elements can develop between the loads and supports and that satisfy (a) or (b):
(a) Clear span does not exceed four times the overall...
I will add a wrinkle to this - an identical project was done at the site doing exactly as shown above (already installed), but the engineer who did the design had no calculations and is no longer at their company.
The existing piles bear somewhere between 10-20ft below grade based on the...
I am working on a transformer replacement project. The new transformer (~330kip) will be located at the same location as the existing transformer so they want to reuse the existing foundation elements as much as possible. The existing foundation is a 3ft 'T' shaped pile cap on (9) 18" dia...
