[Wood Stud Wall] Making this a true Wood Stud Wall design tool.

[hotmailbox]

Hi,

I just found your awesome post regarding wood post interaction diagram. It's super cool. Not sure if you are still active in this personal project and open for further development but I want to contribute ideas anyway. I wish I could be proficient in programing. I am wondering if you can add something to it to make it a bit more practical for every day design tasks. So instead of publishing a chart for specific stud height, revise/create different script to actual design studs for specific conditions (studs at the 1st story of n-story building with different stacking floor framing conditions at walls above for different loading conditions).

Add options to select:

1. Number of stories with stacking wall above.
2. Interior wall or exterior wall (and associated minimum lateral loads or wind load in psf)
3. Conditions of floor/roof framing at each level above (floor/roof joist span on the left and on the right of the wall if they are bearing on the wall, dead & live loads in psf each side, cantilever or not, floor/roof joists continuous over wall or not, platform framing or balloon framing for eccentricity,...)to calculate the loads on to the wall at each level.
4. Wall selfweight in psf
5. Each story height and framing depth to calculate the wall weight and true stud height.

And the script will give options for stud size & spacing with detailed calculations when select each option.

I hope this will reach you well.

Thank you for doing all of this.

You are welcome to take over this project. I am actually becoming a construction lawyer and plan to further develop my coding skills within the legal realm. I am happy to help you with this project. Let me know what I can do to help

Oops, didn't expect to the reply within minutes. Much appreciated.

Congratulations on your new career. What state are you practicing? Did you go to law school after engineering degree? And self-taught program skills? Truly amazing.

I don't have programing skills to take on the project but ideas. The ideas I listed above is what I have been dreaming for a wood stud design tool. Not sure if I can find a like-minded one on Eng-Tips to continue this.

I have a laundry list of projects I working on offline to eventually add to the repo, doing a lot of excel work lately.

I think @JackBandlow may have been working on python3 conversion, not sure I can only tell they forked the repo at some point, but I am very much still the owner of the repo??

In addition I also started the https://github.com/open-struct-engineer group and have been focused on the Concrete cross section tool there.

Sorry, who is Celt83? Should be buddyd16?

[buddyd16]

Yeah Celt83 (eng-tips) = buddyd16 (github)

I like your ideas here.

How I end up using the wood wall tool is to get the capacity values for various conditions and then in Revit I have a Dynamo script that performs load tracking and stack designs using the common spacing capacities.

[JackBandlow]

Yeah, I am mostly self taught in terms of coding and yes I am going to law school after getting an engineering degree. I am not sure what my end on this project is. It has been a few years since I have been involved in this.

[buddyd16]

Just to clear this up @JackBandlow has had 0 involvement in this repo beyond forking it for themselves back in 2019.

[JackBandlow]

@buddyd16 that sounds accurate. I wasn't sure if I had any involvement.

Thanks all for clarifying things up.

It's great that you are working with Revit too. I have quite a few ideas to integrate engineering and Revit but haven't had a chance to implement them because the lack of knowledge in programming.

@buddyd16 Again, thank you for doing this. I hope you will have time to implement my ideas for this tool. If successfully implemented, it'd be the most complete wood wall design tool. I would add one more feature that allow it to specify all stud size & spacing at all levels for a stacked wall system. Do you mind if I relive the thread on Eng-tips to pick other brains for ideas for this stud wall design tool?

Or another feature that can generate entire stud wall schedule for a project based on multiple wall design. Say you name or mark walls A, B, C, D,... and tag them on plans in Revit, then you have a Dynamo tool to get all the input I listed above (number of stories, story height, tributary width each side each level and loads,...) then feed them to design tool which in turn gives you a nice stud wall schedule with different options and ready in Revit. It's totally possible, right?

[buddyd16]

"...because the lack of knowledge in programming."
This is easily fixed, I started here, Automate The Boring Stuff , and advanced to a large percentage of the stuff on here within a couple months.

Feel free to revive the thread on Eng-Tips.

Possible maybe, its actual deceptively difficult to get to what your asking for. The automation of the load take down ultimately requires a general grillage style load analysis program which will also have a a fundamental flaw - it will require users to model in Revit exactly as you would model in RISA/RAM, this means floors can't be modeled over the entire footprint instead they need to be modeled by area and have their span direction defined properly. I started down this path and just hit so many walls with needing users to do things a very specific way that I ultimately abandoned the approach and currently make users manually input tributary widths and area load psf's into custom wall family properties.

Very impressive of what you have done/learnt for such a short amount of time.

No, for stud wall design, I don't think it's easy to have Revit to do the load take down. A simple tool with all manual input and spits out a stud wall schedule that can be used in Revit. Or if possible use Dynamo or PyRevit to get the span of framing each side of the wall at each level for tributary width calculation (with option to select the framing perpendicular or parallel to the wall). Before attempting to get things linked and automated with Revit, a standalone tool should work in concept first. Similar to this one

My ideas came from this one https://youtu.be/ZK598XVWXGU?t=149

How would I change the species and its design values? I don't see the drop-down menu to select and re-populate design values accordingly. Manually input all values, right? Am I missing something?
