Hi, Found some old threads in a similar vein but none really answered my question. First of all this is in Canada so NBCC2020 applies. The deck is up at a ski hill and the snow load is 90+psf (GSL=160+). The occupancy live load is 40 psf. Can I ignore the 40 psf as the snow load is...

Thanks! I was literally just looking through the Simpson catalogue for this hanger (I forgot the model#). BTW, its actually THA422. The THJAs are hip/jack hangers.

Fortunately here I an designing the floor and the roof. I do share your concerns though. I have put the girder as far back as I can get (against the stair well). Once I actually got into the design I noticed that they have a post at the corner of the cant that supporting the porch roof beam...

Thanks. Good food for thought.

I'm designing a floor truss system that has a short cantilever (1'6") that is perpendicular to the trusses. Generally I follow the 150% rule of thumb which would give a 4'6" back span, which will end up being 5'4" to keep the 16"oc truss spacing nice and neat. The question I have is, can you...

No offence but this looks like a school assignment/homework.

I mostly do part 9. Almost all the part 4 stuff I do has a structural package with it so the headers are usually out of my scope.

Thanks. Article looks interesting...printing it off now.

Thanks. I'd call that a 'rule of thumb' for a preliminary design. I'll stick that in my back pocket.

Thanks. I generally start with a 2-ply 2x8 and upsize as loads dictate. I also try to make as few unique things as well, especially when designing trusses, as there are real savings to be had. I guess my irk is probably related more to my own personality. My scope is usually design of the...

Thanks. Didn't occur to me.

A bit of background to my question: I have seen on house plans (architectural and structural) minimum header requirements of 2-ply 2x10 for <6' span and 3-ply 2x10 for >6' span or some similar variation. I have also had people tell me that these are code requirements (BCBC 2024, etc.). When I...

I have some questions about king and jack (trimmer) studs. Some of its generic but also pertains to 9.23.10.6 of the NBCC (National Building Code of Canada). I size headers/lintels primarily using iStruct taking into account loads from floors, roofs, decks, girders...everything. Based on...

For us it’s a manufacturing thing. Our machine can only do max 24” depth. Most of the time that’s enough. Anything bigger goes to our regular table. Last year I did a floor with ~4’ depth. There was no reason from a structural viewpoint. Just what the architect had in his head.

Attached is a picture of the truss. The bearings are aligned with the walls of the seacans. From my understanding, people put a 2x plate along the top of the walls. This is a much larger span than what we normally design so in this case there is a large 1000lb+ uplift (with 24"oc) on the...
