Hello again anons, you've helped me through a few projects and I'm back for more. This time I'm trying to identify which of the indicated framing members A through G in the next few pictures (i think i've got 14 total to give the full picture) are STRUCTURAL vs NON-STRUCTURAL. As usual, I will not take anyone's word on here as gospel, but I'm interested in collecting information and opinions.up front, I'm of the opinion that A should be left alone, B, C, D, and F are non-structural bracing that was only put there to aid in construction, and for the long diagonal boys E and G I'm really unsure (but leaning toward non-structural).Finally, there's the long catwalk along the middle - i'm of the opinion that it's only there as an aid to walking around, and can be replaced with blocking in the joist bays.My goal is just getting this shit out of the way while I improve this space and get some basic flooring laid down (just half-inch OSB for now) so i can store shit without having to balance on joists, which I've already been making great progress on. thanks in advance.
F is just leaning there, with a single nail at the bottom. Barely even worth mentioning.
Will post some snapshots of my house's plans for reference (the roof image is from a prior thread i made RE: roof replacement cost)
top-down view of all the members. Bottom is east, the thicker lines are the storage 2x10s
more for reference
Finally an elevation view
Member A detail. This one is really out-of-the-way so I don't mind if it stays; my sense that it may be more likely to be structural is only due to the care taken to actually frame it out to proper angles.
Member B detail
Member C detail. The fact that it's just landing on that flat 2x4 leads me to call it non-structural
D is basically just floating there, only nailed in from the side and at the top
E is this pair of spliced 2x4's going diagonally from the catwalk up to the ridge. frankly seeing it only nailed from the side into the catwalk makes me also feel confident saying non-structural.
F isn't even nailed at the top
Finally, G is the same as E
And here is a better view of the catwalk.Those are all of my images anons, thanks again in advice for any wisdom.
>>2987382notice the angled 2x4's at 32" o.c. called out in the west view, going up-and-to-the-right to connect to the collar ties. Those aren't present present as-built -- but i know a lot is at the builder's discretion with plans like these (these came with the house in a big roll, the house is this design, built in '98: https://dongardner.com/products/384).
Just consolidate the kicks. They're there for a reason.
>>2987457tell me more. can you show me a diagram of what a "kick" is? This is in Kentucky; I do see results on kickers as a diagonal support to purlins but that does not appear to be what these are (my roof doesn't have purlins)
>>2987483Cut it all out then an put a hot tub in.
cutting the catwalk into blocking has commenced
>>2987377all of those random boards can be removed. the only place that might need attention is at the skylight, its probably not an issue though.
>>2987691yeah, the more i've looked at the plans, the boards, and how they're actually attached, the more i'm with you.in your pic, the member you've highlighted in orange doesn't have that "(AT SKYLIGHT)" note on it, which would imply that it needs to be there continuously across the whole roof -- but there isn't a single one of those up here. Also, what the hell is that random hanging laminated plate on the left side doing? the one with the same stackup as the ridge beam. very odd. that's not here either.
>>2987674>>2987377>>2987378yknow, that's a 50-foot long ridge, and it looks like the ridge beam is only a single 2x12 (instead of the sandwiched gluelam of 2 2x12s with ply inbetween). i wonder if that's okay. ridge isn't sagging from the outside, but still.
>>2987700The engineer must have been very smart, it’s a spare ridge beam for quick repairs, a new one wouldn’t fit through the hatch and you won’t need a crane this way
>>2987483>doesn't have purlinsThey're in the print, but prints are more of suggestions than manuals.
>>2987820is that what this is supposed to be?yeah i agree, these are off-the-shelf plans (literally they were picked out of Southern Living Magazine by the original couple who had the place built), so I know they're very generalized. I actually like this place and don't want to fuck it up. After further review I don't feel like there are enough features to stop the ridge from sagging (particularly at that hip where the other roof comes in), but I want to get some closer photos of how the joists are attached, as maybe they're set up in tension and i'd feel a bit better.
>>2987713That’s because it’s a ridge board, not a ridge beam.
>>2988048Yes, it should have some vertical supports or at the very least be supported at the gables. In the past these laminated ones were seen as magically strong and used for like 24’ unsupported span but definitely not intended to be floating
>>2987377Ok I am by no means an expert but here's what I've noticed reading through the whole thread.>the triple lam on the south side roof in the plansPurlins are used to split the rafter span if on the bottom of the rafters and split sheathing span if on top. Seeing as the gable of your garage volume intersects the main house volume on the south side, they may be to split the span of the valley rafters which are necessarily longer than the common rafters. Or they use thicker rafters. I would check this area.>north side purlins/skylight supportPurlin walls are not typical in skylight framing, it should just have a header and be boxed like any other windows>single 2x12 ridge beamNot structural since you have ceiling joists used as rafter ties, but before you put the floor in I would double check your attic entry has proper double boxed framing, since it cuts the intersecting rafter ties.>the actual boards you asked aboutThey are not structural, delete themLastly,>East facing corner windowsRise and shine early birdAgain no qualifying certs I'm just very interested in roof framing. Best of luck with your project anon
