Any Civil/Structural Engineers in the HAMB house?

I know this isn't exactly hot rod related, but I have asked this question on the Garage Journal and all I get is flak for trying to build it. I want to park a hot rod on a deck....

If your deck can hold a half dozen fat chicks then it can hold a hot rod

 

Depends on the circumference of the fat chicks and the wheelbase of the hot rod.


How tall of a deck, what island, and do you need it rated for an earthquake zone?

 

I can't give you specifics because I'm no engineer, but people around here build decks all the time to hold hot tubs or spas. I'll bet a hot tub full of water and fat chicks weighs more than a hot rod.

 

Can it be done , yes. Need to factor in all your natural factors/ loads then add the live loads (movable items). Depending on # of load bearing beams, the dimensions of the beam may become large and costly. Steel 'I' beams would be an option.

The critical points are the point loads (tire contact patch). Since it is viewed as a single point vs distributed load (hot tub w/ fat chicks) , the design of the decking will need to withstand the force at the location. You could design it so the main beams are the same width as your wheel base.

Covered bridges are/ were all built out of wood. Just a thought.

Not a PE yet, but do hold a degree.

 

What do you want to build it from, I am not an archetect but I do have structural experience, from my time spent in the Civil field. I can make suggestions.

 

'Round these parts you're supposed to have new decks engineered.

 

I'm in Iowa. No Erff Qwakes. Build to hold anything from a couple Harley's to a 34 Ford. Not connected to any other structure.

Anyone seen Nimrod's garage?
That's my inspiration. A large shed **cough** garage sitting on a barely elevated deck.

I'm aiming at 18'x26' footprint shed so the deck will be big.

On a 2200 lb car, each tire patch would represent a 550 lb load, evenly distributed. On a 6" x6" tire patch, this is still 2200 lbs per 1 square foot, really off the lumber property charts.

By the time you get done with the lumber & hardware shopping list, you're better off pouring a slab, unless you want to get around a building code for some reason.

Bob

 

Are you gonna build it?

"The Island" in Iowa?

 

Looking at my rough (CAD) draft, I'm feeling out 26'x38' decking....

All I want to know is lumber req' and spacing. Can't seem to get a straight answer from anyone....

Appears your building the shed and all on the deck?

Check your PM's

 

Not that I have to explain this, but I live in an area commonly called "The Island" to locals do to the fact that it was water locked on all sizes by the Mississippi River and is almost nothing but sand for soil....

And I am certain that this can be done - just Google Nimrod's Garage. And I assume folks put big ass hot tubs on decks that weigh more than a car...

why would someone want to build a garage ona "barely elevated deck".

you'll never get any usefull answers without all the specs.

 

a good idea (off the original question) would be to put a restroom in that bldg since a good bowl is always necessary close to where you'll spend more time away from the wife (if you have one).

 

If you want to know what I am up to, check out Nimrod's shop.

He has one. I want one. Those pictures and my CAD model should draw a pretty straight forward picture for you guys.

I've already heard the "why not just pour a slab" stuff. Simply put, because I don't wanna.

Hell yeah, it can be done. takid455 is right though. The weight of the hot tub would be more distributed. A hot rod would have the weight concentrated on four points. Beams and joists would have to be designed to distribute that weight more evenly to the posts.

That being said, I should stop commenting now because my comments are only based on my own common sense theory and not based on education or experience. In other words, I may not know what the hell I'm talking about. Good luck with this. Again, I'm no engineer but I would also think you would need to consider your soil and subsoil type. You mention that it's basically sand?

 

Forgot to paste the link.

I just checked out Nimrod's Garage. I can see why you want to go that direction. That's pretty damned cool and much more appealing than a garage that looks like hotel lobby or a soda fountain. I'm with ya!

Let's just say I have access to wood. Big wood. Small wood. Medium wood.

I don't want to waste wood, but I want to build it strong enough. That's why I ask for real expert help.

I got this same kind of nay saying on the GJ which is why I am back here.

Background info: my brother has a barn full of....well, a barn. It was torn down and there is a lot of BIG lumber.

x2 very nicely built.

 

Great looking garage for sure, the floor looks like T&G oak, probably 5/4 thick. I just laid out something quick in CAD.. looks like a ghastly amount of lumber will be required.

This very topic was discussed, at great length, on another board that I post on. The load, per tire is the same as the PSI in the tire. I thought that was wrong and about the dumbest thing I ever heard. A real smart guy explained it and it made sense. So the answer is about 32-40 PSI. Of course, the static load is the real concern

 

Only thing I will say is, wood burns real well!

Doc.

 

Amen. I lost one shop due to a fire, I sure as hell won't lose another. 40+ year old wood burns alot faster then the fire department can get there.

Nimrod's shop is cool as hell, no doubt, but I do way to much cutting, grinding, welding, etc to ever work in a wooden shop again.

Good Luck.

 

when i was a kid we used to help out a guy down the street that had a racecar. his garage was elevated. at the end of his driveway the yard dropped off about 20 feet down a hill. he built a garage in the air. pretty cool. from the driveway you would never know it looks like a garage on the ground. we did everything in there, built cars, engine swaps, jacked cars never a problem. and its still there today .as for the 2200 pound per square foot comment. i dont think each wheel would weigh as much the whole car put together. equipment trailers bounce down the road with 2" oak decking and backhoes dont fall through them.
