how to connect bracing to steel beam?

how to connect bracing to steel beam?

(OP)
I'm wondering which option would you choose and why.

OPTION 1: bracing is connected to steel plate that is welded to the secondary steel beam as shown in picture. Secondary beam is bolted to primary beam.

OPTION 2: bracing is connected to steel plate that is welded to the bottom of primary beam





OPTION 2:



I think option 1 is better since tension forces in bracing acts in the middle of primary beam, but bolts (connection of secondary beam to primary beam is more loaded - tension in bolts).

Option 2 looks simple but it may want to rotate primary beam since tension force from bracing is actiong on the bottom.

Thoughts?

RE: how to connect bracing to steel beam?

Option 1 is fine as long as the additional load to the bolts is taken into account. I would also be comfortable w/ Option 2 since it is a tube. It would be a different story if it was a WF.

RE: how to connect bracing to steel beam?

Do you have steel grating for your floor?

dik, its a canopy... glass is on top of beams.

RE: how to connect bracing to steel beam?

Did you want to construct a rigid portal and avoid the bracing? A visual thing.

One side of canopy is glass (no bracing in roof plane) and the other half is plywood + metal (bracing in roof plane)
in X direction masonry building provide horizontal stability of conopy
in Y direction there is a bracing in roof plane that is fixed to masonry building (concrete ties) so the forces are transfered to masonry building



RE: how to connect bracing to steel beam?

Is the bracing within the plane of the roof or the end wall. If the end wall, then, ignore my comments. Your picture appears that it is in the plane of the roof.
