You can find all your stud lengths on your rake walls with a Construction Master calculator. Repetitively.

Re: Construction Math For Dummies


Simply put, rise, run and diagonal. run being 16"

Put the pitch in the calculator first, 4/12 5/12 or whatever.

16 inch run, then hit rise. It will tell you how much it rises in 16"

Then hit diagonal and it will give you the length of the stud at the top plate.

You'll need to write each stud length on paper.

Making a cut list.

You'll need to add each rise to your original stud height, for example. Your first stud may be 92-1/4"

Keep adding the rise to your starting point. My starting point example was 92-1/4"

repetitively

The only problem with that Mike, is that the walls do not behave like rake walls.

Their pitch isnít tied to roof pitch and variable.

Although...by just looking at the prints quickly, it seems that some are identical, in that they match each other.....but again, not the roof pitch. (I think....Iím out at the farm and the prints are in the office.)

Question....
Can I enter a specific value for pitch...say 11.26 degrees into the CMaster and generate the stud heights?

That....would be a huge time saver.

You can enter 11.26 as a pitch and as long as itís consistent than the CM will spit out stud lengths.

Can we get videos of you guys scratching your heads?

Sorry...couldn't resist.

Re: Construction Math For Dummies


Lots 'o fun! Top down the only way I know how to do it.... the rake walls pitch needs to be figured from the theoretical rise at each rafter minus the differences of rise from ridge. And each rafter rise needs to be figured from the run in plan using roof pitch. To figure the runs in plan gonna have some trig to do.

You get the rake pitch it's easy to calculate the stud lengths. You also get the common rafter difference length on that rake wall, for 16" (in pic) o.c. by figuring the two lengths and subtracting.


The beginnings kinda look like this??? Yup tell me to go get 'D Sure as hell would love to see another way

It's just some basic trig and Pythagorean math. Maybe some mental gymnastics easy peasy.

Kind of believe it might be easier, especially for adjustments on the fly on site to do the math vs cadding it out. I'd probably triple check the math in Cad, just to be safe.

Re: Construction Math For Dummies


It looks like an Alabama trailer After the Tornado.....

How do you keep the flat top of the roof from leaking?

The roof section doesn't appear to be thick enough for the roof rafter depths needed on the longer spans.....IMHO

The ratio of exterior wall to square footage is sub-moronic in my opinion.

How do keep inside corners dry and tight under roof that only over hangs an inch or two?

Love to see the HVAC plan....It needs 2x + Heat and cooling vs a "normal" wall to floor ratio home....

The good news the Tax assessor might end giving the HO a yearly grant till they move

How can the designer claim all the fees for the design when the plans aren't finished?

If you bring this thing to life Dr. Frankenstein, are you partially responsible or fully responsible for any Civil torts or code violations?

Can't the building meeting the intent if not the actual verbiage of energy building codes, maybe at low elevations in Hawaii?

Would any bank loan enough money for a mortgage that approaches a fraction of its construction cost?

Can you afford the HO walking away with out paying for all the work you have done, if they suddenly develop commonsense?

Successes have a thousand Fathers, failures always are illegitimate children of no-one.

Re: Construction Math For Dummies


T-Wax @#34 Looks like you're 95% there, But, the roof center(ridge) is aways from the line you drew... and the Roof is "rolled" over the ridge area ~ 2 feet, to add to the cost of the roof framing on every one...

One could "balloon" frame the studs temporarily, using a sloped ledger board to set the lower end of the rafters on, then cutting the studs to fit under the roof deck, having erected a temp ridge a the 'Missing' ridge height, chase the rafter down a jackline to intersect the off grid wall line.

Hopefully all the roofs spring from a constant wall height at the low point? 8-9' aff?

You could frame this in big tin shed, and haul out the rooms on medium sized trailer.

Good luck, keep posting as the wheel turns please
