Adapt PT
Adapt PT
(OP)
I created a model using Adapt Builder. I am exporting the support lines to Adapt PT to design the PT tendons and reinforcement. I am using Adapt Builder Ex Build 1 and Adapt PT v7.20.
1) Let’s say my design strip (half the distance to adjacent support on each side of support line) includes beams/columns/slab. When I export this strip to Adapt PT, I have a choice of “two-way”, “one-way”, or “beam”. My design strip includes both T-beams (rectangular beam plus slab as flange), two-way slab, and a cantilevered slab. Which should I choose, “two-way”, “one-way”, or “beam”?
2) In the same situation as above, should I choose “beam” (I’d like to determine my beam tendon profile and reinforcement), and after clicking “Save and Execute Analysis”, should I modify my profile using ONLY the beam tendon profile, or should I use the EFFECTIVE HEIGHT of both beam tendons and slab tendons? Please remember that I am using Adapt PT v7.20 and I cannot make multiple profiles as in v8.

RE: Adapt PT
The beam design and the slab design must be kept completely separate.
The slab tendons have nothing to do with the beam and its depth and cannot be included in any related calculations.
RE: Adapt PT
Please tell me if this process is correct:
1) I designed my slab PT tendons and midspan bottom bar reinforcement in Adapt PT exclusively. I took a 12 in strip of slab and modeled accordingly (proper spans, supports, loads, etc.). I then distributed the tendons in klf (in this case 7.7 klf and 12 klf) and placed proper midspan bottom bar reinforcement (#4 @ 18", etc.)
2) To model the PT and reinforcement in the beams, I am using Adapt Builder Floor Pro and Adapt PT. I created the model in Builder, created support lines, and am exporting the support lines to Adapt PT. For example I have a four-span support line: 1) 15' cantilevered slab, 2) Tbeam (rectangular beam with slab as flange), 3) Shear Wall, 4)Tbeam. I have a two-way slab as well.
I want to model the beam PT and reinforcement, I export to Adapt PT and click on "beam" (out of choices "two-way slab, one-way slab, and beam"). I run my analysis, set my tendon profile, make sure P/A, Wbal, and 6sqrt(f'c) are satisfied. Is this a correct representation of the model? For the cantilevered slab span (1) and shear wall span (2) I am placing zero tendons. In the beam I am getting a large amount of tendons (15 tendons for 24x36 beam with a trib width of 23'). I'm having trouble believing this is a correct representation of the model.
Also, I talked to a representative of Adapt and they suggest I place all tendons in the beam and zero tendons in the slab (they consider this harmful tendons as it raises the effective height of your tendons in the design strip). On previous jobs (parking structures), I have merely done the 12in strip design for slab and T-beam design for beams. Another question, should I be using the design width or effective width for design in Adapt PT. Adapt PT uses design width but I've read that using effective width is a better representation. But to use the effective width, you cannot import the "solution" back into Adapt Floor Pro.
Haha, sorry for all these questions, and I do appreciate all the help. Thank you.

RE: Adapt PT
Sounds like the software is limiting your design rather than designing the way you want to. Not a good way to design. Get decent software.
You should use effective width.
You should not include the slab tendons in the beam. The support person you talked to does not know what he is talking about.
