Point Load on Lintel Beam

[pdev67]

hi there, I have question. Framer has put the beam over the garage door lintel(attached picture). there is bonus room over the half garage. Any solution to fix it
?

 

[Ron]

Move the door. Framing at the door is not done correctly either. What is that beam supporting? It is parallel to floor joists.

 

[pdev67]

Beam is supporting the load bearing end wall of the room above. what the framing at door should be?

 

[BridgeSmith]

Is the header or the studs inadequate to carry the load from the beam? Doesn't look like the bending capacity of the header would be a problem, but I'll defer to Ron on the framing configuration.

 

[Ron]

Hinge side of the door should have double king studs, not single.

It looks like the top plate has been cut to allow the beam to sit inside. Was this necessary? Is the beam so deep that it couldn't sit on top of the top plate?

Studs look like they are poor quality with a lot of lost cross section. Was this rated lumber that was used?

My money is also on that LVL header likely required more than 1 1/2" of bearing length with that large of a PT load on it.

 

[BridgeSmith]

I might take that bet, jayrod. Those look to be at least 2x6 studs; at 350psi allowable compression perpendicular to the grain, that one jack stud should be able to carry over 2800 lbs. Add some nails or screws through the king studs (don't know if that's typically done) and the capacity would increase. It could be plenty adequate, depending on the beam load.

 

[jayrod12]

But not the way they framed it. With the 2x sill plate between the LVL and Jack, the crushing of that sill will be the governing factor.

2800 lbs is only 50 sq ft of floor. A beam of those dimensions is carrying significantly more than 2800 lbs, or it's a gross oversizing of the floor beam.

 

[BridgeSmith]

Pardon me for not being clear, jayrod. The 350psi is the compression perpendicular to the grain on the 2x at the top of the door frame, which bears on the jack stud, the compression parallel to the grain in the jack stud is about 3 times higher.

Not saying it's for sure adequate; it will depend on the magnitude of the load from the beam, which we can only speculate on at this point.

Of course it would have been better with a second jack stud that directly supports the LVL header; no argument there.

Thank you so much for all of your input, What I understand is, to extend the length of the lintel beam and use two Jack studs under lintel beam to increase the bearing both sides and 2 king stud beside it both side. Please correct me if I am wrong

 

[jayrod12]

Without more information, we cannot say for sure whether anything is required.

I suggest you hire a local structural engineer to take a look.

 

[pdev67]

I have attached the plan I have. I tried some calculations and load on garage beams comes out to be 1055 plf ( based on floor LL 40psf, DL 20psf, Roof SL 25psf, DL 15psf, Wall load 100plf). Garage beam is 22' long, so reactions at ends 11605 lbs. Door lintel beam is getting load of 11605 lbs. end reaction at lintel beam 5802 lbs. we need to provide jack stud to take load of 5802 lbs on both side. can you please check?

 

[jayrod12]

No we can't. You could hire a local engineer to provide the sealed calculations

 

[pdev67]

Okay, I will, thank you so much

Have you considered deleting the door? Not sure there is much purpose having a door in that location as you would walk straight into a vehicle.

The 12" dia. concrete piles are an unusual feature in the garage. You might ask the local engineer to review that feature as well.

Unfortunately, the entire project looks poorly done. From the poor quality materials (wood & windows) to the poor construction techniques. The plastic windows only have a design life of 15 years or so making them a poor investment.
