Cantilevered vs. Simply Supported CMU wall?
Cantilevered vs. Simply Supported CMU wall?
(OP)
So,
I'm an EI and I just finished working on this small (about 10' deep x 10' tall x 16' wide) CMU enclosure to be added onto the side of an existing building. (It's basically an outside storage area for this retail store) Anyways, after I did my calcs I handed it over to a co-worker to glance over it and one of their marks was to analyze the walls & footing as a cantilevered system for the period of time in construction where they've built the wall and haven't attached the roofing to the top yet.
I've never done that in any other masonry structure and I'm really curious when others have taken the same approach.
Small note: the roof diaphragm consists of 3" deck that span from clip angles anchored into the existing wall spanning 10' onto the CMU wall.
Thanks!
EDIT: Thanks for the replies everyone.

For the forces in the plane of the wall - lateral shear loads to the CMU wall as a shear element, however, it would be cantilevered, as opposed to fixed, anyway.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
