Cantilevered Wood Diaphragm 1

[ltfdrsn]

Hi,

I am designing a flexible wood floor diaphragm with a deck. So essentially, the deck will be having a cantilevered diaphragm because there is no shear wall below the cantilevered part of the deck. I would like to get some tips about how to approach to a condition like that.
I was planning to use hold downs.. I would be glad, if there is an example that you guys suggest..

Thanks for the tips..

A sketch of the situation would go a long way to help get meaningful answers.

Hi @Jayrod12,

I attached the sketch.

Thank you,

At only a 5 ft cantilever, I would make sure your diaphragm nailing has enough capacity to transfer the small portion of load into the shearwall and be done with it. It's very long and narrow, I can't see anything that jumps out at me as concerning. Is it transferring any lateral load from walls above?

@jayrod,

There are walls above sitting on the shown diaphragm but not at the cantilevered section.

Then I don't really see an issue, that portion of the floor is essentially just going along for the ride.

Exactly! Thanks ! @jayrod12
