A Few Ways To Make Floor Framing Structurally Stronger For Garage Loft - Building Education Part 7

[@timmyfoyle4488]

I converted my truss roof without steels just doubled up the 4x2s built supporting walls each end and collar ties all boarded out strong as anything

[@gregvancom]

The engineers might not like it:)

Could i attach a rim joist to a steel column? my building is built similar to a pole barn with 4 steel load bearing columns on each side. and I’m adding a second floor. I don’t have the option of stud walls because my “girts are 2x6’s laid flat. I could notch out a stud wall but it would be extremely time consuming and i don’t have the space to fur out a stud wall.

[@gregvancom]

I can't provide engineering advice, but would think if you could, you might need to attach some type of support bracket under the beam or ledger also.

[@frankly2677]

@@gregvancom thank you for your response! Your videos have helped a great deal to visualize and understand components of building.

I wanted to structure the 2nd floor of my garage that way and contractor friends with basic skills disagreed. In the end I did it their way and I'm unhappy with the results.

[@sergemarlon]

What did you guys decide to go with and what didn't you like about it?

[@gregvancom]

Yes, we need more details.

[@MattNis1]

How about I-Joist and a few LVL

[@gregvancom]

Absolutely.

[@eschrader]

Terminating it above the large garage door can be a challenge. I'll have to look up the load on my strongwall system in the plans

[@eschrader]

I am thinking instead of this to do about 4 or so of the 4x8 rafter lifts, maybe 2 over the large garage door too. The only issue is I would have to leave some space between them all and hang down some garage lighting. Easier than lugging stuff up stairs since the lifts have motors. Technically some heavy duty ones can lift dirt bikes but I don't want to deal with suspending that weight from my ceiling even with the 2x6 walls. Another issue is the space above the collar ties is not as easily reachable.

[@gregvancom]

Yes, that could create a structural problem that will require stronger connection points.

[@celyl]

when cost is no object. It would be more economical to add steel beam member ($1500 installed near me) and reduce joist length by half. I like the double 2x6 posts on 48 center.

[@gregvancom]

You're right about design and cost.

[@stevedeweysmith]

More beams and studs and larger beams and studs will increase strength, but they will also increase costs.

[@gregvancom]

You usually can't add more lumber with out spending more money.

[@carnaud]

I still don’t like the idea of the whole second floor hanging from lag screws. I would support the ledger with jack studs periodically…like at least every 32”.

[@eschrader]

You can't really put a lot of dead weight up there with that span so lags aren't that bad imo

[@carnaud]

@@eschrader Depends on the floor joist size I’m sure. Putting jack studs around the permitter would support it. I’m just afraid lag screws would snap.

[@gregvancom]

I agree with Eric and structural requirements for construction like joist size, footing sizes and leger attachment usually depend upon the use of the building. For example storage or a workshop might require a stronger structure than a loft or living space.

[@MrSubliminalStudios]

Holy smokes that garage got expensive

[@eschrader]

3x12x20' at $120 ea would be $2500 for 12" joist spacing. Whooo eeeeee. But I guess if you do anything with LVL the price gets up there too.

[@gregvancom]

What about 6x14's spaced 1 inch apart:)

[@gregbowden5876]

If you jack everthing your ok

[@gregvancom]

By jack you're referring to framing studs under the joist?

[@concerned_2023]

A lot of effort for two feet.

[@gregvancom]

Yes.
