    Cantilevered Beam on Wall

    That was my past life. I now am designing roof trusses, EWP roof and floor systems (including beams). Key word being designer. As an engineer I know the difference between the two and I stick to my lane. A lot of the questions I post are for my curiosity and learning.

    Cantilevered Beam on Wall

    Taking into consideration that I am a thick-headed chemical engineer and that the software at my disposal does not allow for straps, springs, pinned vs roller bearings, nails, screws, duct tape or anything else of the sort, would this be the best representation of what would happen if I strapped...

    Cantilevered Beam on Wall

    In a sort of related question, maybe for KootK as this applies to Canadian residential construction, what is the best/normal way to install this beam? Placed on top of the very top plate (in this case wall framed 9.5" lower) or built into the wall?

    Cantilevered Beam on Wall

    Thanks, my thick head is getting it.

    Cantilevered Beam on Wall

    Trying to sort out the reality of what's happening and the fiction from the software. Another question I have is what is the real load on bearing 1. My first example above shows a factored load of 18000 lbs. If I model the beam as per below its only 5700 lbs. My guess it will depend on how...

    Cantilevered Beam on Wall

    To clarify, the software automatically changes the bearing width to the beam width. In this case a 3-ply LVL (1.75" x 3 = 5.25"). I suggest that the software isn't smart enough. Wouldn't use it to build a bridge (which it couldn't do anyways), but works good enough for a wood frame house in...

    Cantilevered Beam on Wall

    BTW, I hate the term. It is technically incorrect, especially if its sloped (I believe). The material used is an i-joist so I guess it is now in the vernacular. My bigger pet peeve is the use of the terms jack stud, trimmer, and cripple, with cripple being the most inaccurate IMHO.:ROFLMAO:

    Cantilevered Beam on Wall

    Roof joists. Just snow and DL.

    Cantilevered Beam on Wall

    Hey, To clarify the loads: Load 0 is the self weight across the whole span. On the cantilever are point loads from the roof joists above (loads 2, 3, 4 & 5). In reality the joists continue over the entire span (24"oc) but the software is showing it as a linear load (load 1). To simplify...

    Cantilevered Beam on Wall

    Hey, I come across the situation often enough and I want to know if I'm designing things right or if I am cheating. I use iStruct but I imagine other software is similar. When I put a beam in line with a wall with a cantilever I can only get the beam to pass if there are two bearings. I get...

    Blocking to counteract moment of beam.

    It is kind of annoying. This is very helpful. I don't have any issue with the concept of bracing, more like what is enough bracing. I've been reading a lot more about sheathing/diaphragms lately and now realize just how much lateral force plywood resists/transfers.

    Blocking to counteract moment of beam.

    Thank you so much. I guess I don't have to worry so much since most of the time my beams are either sheathed as part of a floor or restrained by joists or trusses.

    Blocking to counteract moment of beam.

    Hi, I have a situation where a beam is failing due to excess moment. This beam is 18" deep (LVL) and is running parallel to 11-7/8" deep I-joists (top of beam and top of joists are flush). The beam is supporting is a single column at approx. mid-span taking a very large point load from the...

    Ridge Beam Moment

    Sounds great. Sorry for the delayed reply. I have a pinched nerve in my neck which is limiting my screen time amongst other things. Can't get into my doctor until next week.

    Ridge Beam Moment

    Born and raised in Castlegar myself. Also now in Calgary (17 yrs, 30 in Alberta) but my design work is all Kootenays and Okanagan.

    Ridge Beam Moment

    Thanks KootK. Does the Koot at all refer to the Kootenays? Just wondering. If too personal, disregard.

    Ridge Beam Moment

    Hi, I am designing an LVL ridge beam and its failing on moment. Do the rafters (hung on each side of beam) count as top bracing? I wanna say yes but would like an expert to weigh in. Thanks!

    High Snow Load on Deck

    EngDM: Thank you! I have been looking for that exact statement. I have read part 4 in its entirety but its not exactly a light read so no wonder I missed it. I guess I will have to put a copy in my bathroom. :ROFLMAO:

    High Snow Load on Deck

    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...

    Cantilevered Floor Truss Backspan

    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.
