@bausk Can you review the following PDF?

Can you please verify i have all the correct sizes that you speced?

I also have a couple questions in red.

btw... please send along a jpg of your logo, if you have one. Would like to add it to the title sheet, as well.

Current input data are the model and design codes.

Structural design is based on the State of Wisconsin building code, all data will be derived from there if thre's no further details:
https://docs.legis.wisconsin.gov/code/index/index/t/uniform_dwelling_code

If there are any additional input data (live loads, equipment not taken into account in the current BIM etc.), please forward it to me.

@bausk

General workflow question, in your workflow, can you tell (easily) what things (members) I've changed or deleted or added? -- a 'diffing' tool perhaps?

Or do you still rely on the architect (or whoever) to manually ping you of the changes, via screenshots or the like?

@bausk Alex, would you happen to know the answer to this?...

Hi @bausk

In response to your comment here..

Calculations assume that the joist grid within axes 4 to 6 over Floor 2 Living Room (2) as well as the boundary joist at axis E transfer loads to the structural wall at axis E.

Actually that 'L' beam at gridline (4) is transversely loaded (point load) at the intersection of gridline (4) and (E).

That structural wall at griline (E) spans from the intersection of gridline (5) and (E) to the intersection of gridline (6) and (E).

Thanks.

@bausk
just to verify, are our corresponding gridlines are the same?...

this is what i have:

only ask because that w6x16, that you have at GL (3), is at GL (2) in my model.

Thanks.

Hi @bausk

At the garage location, for whatever reason the contractor did not align the ridge beam with the floor beam below. There's a 7" offset. :/

See following commit for illustration --> d31a024

Was wondering if you could do a quick calculation on what size those new LVLs would have to be to accommodate the roof load.

Let me know if you're able to jump on this relatively quickly.

Thanks.

Please confirm or elaborate:
For the redlined elements, only the section size is subject to design, i.e. shape types, steel grades, timber types are not to be altered?

Hi @bausk,

Curious, what authoring program are you using to do your calculations?

Do you mind, uploading that file as well? Not that it would happen, but it would be fun to see others riff off it.

Thanks.

You might want to take a look at this. Here's a column analysis example made with Excel:

https://github.com/bausk/IPythonAnalyst/blob/master/Sources/AISC_design.xlsx

Here's the same analysis made with IPython Notebook (sans AISC sections which I'm still figuring out):
http://nbviewer.ipython.org/github/bausk/IPythonAnalyst/blob/master/TestAnalysis-Column-AISC.ipynb

Each has its strong and weak points, For example, the ipynb doesn't normally let you hide code or insert evaluated expressions into text blocks, but it is much more explicit, text-based and able to be reviewed instantly.

Also the second example has a very serious improvement: automatic units of measure, it's a failsafe against many common errors.
I can input in whatever units I want to and even mix customary and metric units, the interpreter takes care of correct conversion. One also doesn't have to have Python installed to review it; or we could in the meantime set up a common server that everyone on the project would have access to (just speculating here).

Next step is including images into ipynb. I also look into building a tool that would automate conversion from xlsx sheet to a python algorithm, it would be a big deal for engineers that use Excel - and that's basically all of them.

Follow up if you have any thoughts or comments as to what looks preferable.

@bausk, was wondering if i should be concerned about the lateral stability of those corners of the house with multiple windows--these locations...

Should we be entertaining some type of moment connections in that framing?

Thanks.

Hi @bausk

Can you size remaining members? The following PDFs show their locations...

Not that alot has changed, but i also uploaded a new IFC file here, if you need it:

They are starting to frame this week, so if you could get to these this week, that would ideal.

Thanks, Ryan

Hey @bausk

Could you answer the following couple questions from the steel supplier? Particularly questions (3) and (4).
Associated documents can be found here: a5925e1
or..
Lake_Kegonsa_Home\Transfer\Endres Mfg_20141222

Before we make up a drawing for approval, please clarify.

1.  We will be making the steel columns, using 3” sch. 40 pipe. We do have adjustable base for these, similar to the FHA posts.
   

I'm assuming this is okay.

2.  W12x28 – Your choice will be W12x26 or W12x30.
   

they read the plan wrong, it 'is' a W12x26. It's the beam along H

3.  L8x4x9/16” is not made. We have in stock L8x4x1/2 and I attached the mill certs with it. About 53 KSI. Can you make this work?
   

4.  There is a double LVL connecting to the L8x4. Toby mentioned it would be difficult to determine exact location. Can you draw up some type of plate hanger similar to what I attached that would work. Toby said he would like to field drill the location into the L8x4.
   

Ryan,

I have committed the document, Rafters.docx, with the calculations for rafters of the three roofs:
https://github.com/OpeningDesign/Lake_Kegonsa_Home/tree/master/Structural

Please review and express your wishes on what to alter in the format of the calculations. I would like to know what format, etc. you would like to get, what changes should be made. Perhaps something more version control-friendly?

Hi @bausk

Could you make the beam at gridline (H) the next priority?

It is transversely loaded at the intersection of gridline (H) and (2).

Thanks.
