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...
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...
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...
I have designed several roof truss systems for garages/storage buildings constructed with seacans as the 'walls'. They are increasingly popular, especially with homesteaders. Most of the time the trusses bear on the walls with a sill plates running up the 40' (or 20') sides. We have a...
I'm working on a floor and roof design for a 6-plex. The structural drawings are well laid out and there are good schedules for all the wooden beams,columns,joists,etc. However, there are a bunch of columns that are identified as either SC, S2C, S3C, 2S2C, or 2S3C. I am presuming these are...
Hi,
When selecting hangers does the wood species for factored resistance apply to just what the hanger is attached to or does it include what is hung? For example, if I have a D.Fir girder and I want to hang an SPF truss on it, do I used the factored resistance for D.Fir or SPF?
Thanks in...
Trying to determine the point load at the end of a cantilevered joist. I'm a chemical engineer so please forgive me. The wall above has a dead load of 80 plf and a snow load of 110 plf. If my joists are at 16" o/c is my point load 1.333 ft*190/2=127 lbs? If not please help. I know its a...
