    Forum Clutter - Students (and others) posting in this forum

    Did this discussion of bad posts actually veer into bicycle designs? I'm not sure, I got a bit TLDR in the middle of the first page.

    For fun, how would you analyze this joist?

    IEBC Allowable 5% Gravity Increase Example

    Is there any full-on legit documentation on construction drawings of the 30 psf being actually designed for back in the day? Versus "well the code said 30 psf"? My main concern here is that PEMB is well-known to be designed right up to the verge of failure with every possible reduction and...

    I have one of those for a header in my house.

    Replace partition wall under roof joist with beam

    rafter - roof rafter, shingles are nailed to the sheathing that's nailed to the rafter, joist - -- ceiling joist - insulation sits on it and maybe a vapor barrier and the gypsum board. Generally the shallower the roof, the more thrust you get and need to resist. This kind of construction...

    4x8 vs 6x8 SYP #2

    As a footnote, the 2017 Woodworks design example has 4x8 end posts for shear walls, if we go that route, the "green" dimension only applies to the 8" dimension.... which is a bit funky, if you ask me, I haven't looked too closely, so I can't say if they use the net dimensions for the post...

    Insurance Question

    That's got to be the best KootK drawing in years.

    4x8 vs 6x8 SYP #2

    IBC is generally "after" the design standard so it would override the design standard. As a precedent the 2000 IBC modified a LOT of ACI 318-99 in Chapter 19. I don't know why anybody would bother with green dimensions and checking things based on those section properties because they WON'T...

    Insurance Question

    Well Koot, you had no demonstrable intent to deceive, so I'd argue it's a typo. You didn't steal the guy's license. Further, Unabomber was 1990s, but I suppose you're right that the start was back in 1978.

    Upgrading Existing Building Joists?

    I agree in general, Bey, but the IEBC would more rationally be applied to load combinations, and dead load alone is a load "combination" therefore it always read that way. You wouldn't just check for "total load". You check for changed dead loads and you check for the other combinations, if...

    Engineered Shear Wall Design in IRC Prescriptive Brace Wall System

    Not caring is not the standard of care. Your defense expert, should you need one, is going to have a tough road with that mentality. Lack of calculations certainly looks like Lack of care to a jury. Having at least a rough feel for the diaphragm load (or the code-required capacity via the IRC)...

    Ponding Load

    I understood what you were asking already. Alright fine, for the curious..... I'll retract my previous "I was disappointed by it." But it's pretty abstruse, and there's even discussion in the commentary. So that kind of follows with what Pham was going at. This isn't the whole thing...

    Upgrading Existing Building Joists?

    Dear lord. I suspect most rational engineers would apply this analysis for the increased snow loads to the bays and the affected girders. And not cheat the analysis by using the "old" (known to now be incorrect and unconservative, i.e. unsafe) ground snow load. Remember you are on the hook for...

    4x8 vs 6x8 SYP #2

    Source: 2018 IBC I'm not convinced there are established "wet" dimensions for green timber, but I'd strongly suspect typical design practice is to ignore this, and I'd point at the Thompson design example as a west coast design example that uses the 'dry' net dimensions for various...
