SIZING: Monster for glulam beam. Install garage door under load-bearing column

[kashieda]

Was the ridge centered over? If so, it might work with inclined supports against the sides of the gate. They can take the compressive load as long as the beam takes the tensile load that is created.

I think one can go for 90x270 even if it is highly utilized. Both short- and long-term deflections are small, so one can be a bit bold here As mentioned, the overall structure needs to be reviewed when choosing the beam. Since the column is 115x115, a 115 wide beam simplifies the attachment, especially if the new columns are 115x115. It may be a bit over-dimensioned, but it simplifies quite a bit. Also, don't forget to brace the beam laterally at the top at the supports.

Why not make a "takstol" at the gate to avoid the point load above the gate and bring them down to the ground in a more attractive way.

Why not make a "rafter" at the gate, then you avoid the point load in the middle of the gate and can bring them down to the ground in a more attractive way.

I agree.
If I understand correctly, nothing special is needed above the garage door, provided that the load from the roof beam is transferred down the sides of the garage door.
But there are many ways to skin a cat.

Placing a beam over the gate is much more rational and imposes much fewer requirements on the execution of joints, etc., than what a "takstol" would do. I would recommend using a beam.

If the column with the apex load is 115x115, I would suggest a beam with the dimension 115x225 (borderline) or 115x270 (preferably).

If the column with the apex load is 115x115, I would suggest a beam with the dimension 115x225 (borderline) or 115x270 (preferably).

Thank you very much for the help
