Frame design for an overhead door oprning

Frame design for an overhead door oprning

Frame design for an overhead door oprning

(OP)
I appreciate if somebody can direct me on some sources ( in simple language) guide me in design of frame around a approximately 10ft (wide) by 12(height) in a metal siding wall.

This opening will be located close to an existing louver(please see attached pic, which I don't know what will be the influence.

I like to know the loads that will be on the door frame and the load path.

If the owner decides to leave the opening open (not installing any door) does the frame see no load?

Also how will be the loads if they use vinyl strips rather than actual overhead door.

I appreciate directing me in this matter.

Respetfully,
Your less experiend colleage.

Does any one have a practical detail of framing to the grit above and from side?
I forgot to ask in original post.

RE: Frame design for an overhead door oprning

Cut the lower girt for the door. Run a vertical jamb on each side up to the second girt. Beef up the second girt if needed.

Use channels, angles or tubes.

The exterior skin spans between girts. Do math using C&C loading. It should be pretty minor.

manstrom (Structural, thank you for your response.
What should I check the second girt for? What loads?
Where are you refering by exterior skin?

Do you know or have a reference that I can follow calculations and checks needed. I would greatly appreciate if you have or know any sample calculation that I can follow the steps.

Thank you very much - for any help.

RE: Frame design for an overhead door oprning

The girt that would be at the head of the new door is now taking the wind as point loads from the jambs of the new door, and thus is trying to carry more load as the lower girt is cut away. If you have modeling software you could model the panel from the ground up to the 2nd girt, apply the appropriate wind load, and check the new loading on the girt. Note that the columns now will technically receive a larger moment due to the wind load from the girt being shifted upward, which may be worth a look if the magnitude of load increase looks significant ( probably greater than 5% increase).

structSU10 (Structural, could you please draw the loads on each element so I can clearly see that. I greatly appreciate it.

RE: Frame design for an overhead door oprning

If you can't draw the loads yourself from his description then there is a good chance you should not be doing this work yourself. His description is more than enough for anyone with the slightest bit of structural design experience to draw for himself and analyze.

He's not getting paid to do your job for you. Think about it rationally.

The wind load is going to exist (never believe an owner when he says he's going to leave it open permanently, that only lasts until the first winter when it's cold and they decide to close it in).

You have to provide framing to get the load to the pre-eng frames.

Before your modification the wind load went through the girt (at the 7.5' mark) to the corner frame and the vertical member beside the existing louver.

Since you are removing this girt you need to transfer the load to the next girt (which may require reinforcement for the additional load it will see now) via some sort of vertical wind column on each side of the door.
