Tilt Panel Opening
Tilt Panel Opening
(OP)
I am assisting in the design of a tilt panel building. The building has a 7.25" tilt panel that is 39' long and 18' tall with a 3' parapet. There is a 34'x12' opening in the panel with 3' and 2' pilasters on either side.
Are there any restrictions with the size of the opening in a panel? I am getting double mat reinforcement with ties at the jambs and I am designing the opening as deep concrete beam. In addition, I am also bracing the opening at the ceiling height to the joists. The panel also is OK in terms of deflection per ACI 551. The vertical stress in the pilasters is also OK.
Is lifting going to be an issue for this panel?

Key thing Newbie that you have already done- get your boss involved, those are good questions for your mentor. This is not a cookie cutter panel by any means.
Also if all of your panels along that wall are the same, you may have some in-plane shear wall issues that you will at least need to pay attention to.

I think the "deep beam" refers to the 34' long x 6' deep head section. But the legs of the panel, 12' high, 2' wide, and only 7.25" thick, are the big problem with both strength and ability to erect. He talked about two layers of reinforcement and ties in those skinny legs, and I don't like the sound of it. Even if you could satisfy the in place strength provisions and get it cast, the legs would crack during erection unless cast on a tilting bed.
