    ASCE 7-16 Loads on Canopies (30.11) - What about a canopy with a sloped roof?

    Hey everyone, I went down the rabbit hole a bit and want to ask everyone else how they deal with it. We do a lot of projects with big sloped roof overhangs (think big porch roofs over 10' deep) that are not at the roof level. For the components and cladding loads for wind blowing toward the...

    LGMF - Ledger over gyp board at fire wall - does this exist?

    For anyone wondering, I stuck a joist through the wall every 4' and headed everything else off at the wall with beam right next to the wall.

    LGMF - Ledger over gyp board at fire wall - does this exist?

    @XR250 - same for this case, the trib width on the ledger is like 3' max. My plan would be joists to ledger w/ typical clip, ledger to studs w/ screws. @phanENG - I looked at those. I don't think I can get them to work (this is a mezzanine framing into an existing wall at mid height) I'll post...

    LGMF - Ledger over gyp board at fire wall - does this exist?

    I would envision using a track as a ledger with the track fastened through the gyp board layers to every stud, so it should work since the spans are only 16" between supports. My bigger question was if there are any screws or assemblies rated for this (we could use a C8 as a ledger if we needed...

    LGMF - Ledger over gyp board at fire wall - does this exist?

    Is anyone aware of a detail to put a track section against an existing LGMF stud wall (fire rated) that is rated (has an ICC/equivalent report) for use over 2 layers of gyp board similar to what simpson has for wood ledgers used over a layer or 2 of drywall? Thanks!

    Wall Footing Connection - Rebar or no rebar between slab and footing?

    I'm doing a peer review on a project and this is one of the few big ticket items I came across. Everything else is super clear, black and white with regards to being allowed per code and meets design rules (strength/etc), but this was the one gray area where I wasn't aware of any code provision...

    Wall Footing Connection - Rebar or no rebar between slab and footing?

    Hey folks! Scenario: wood stud wall sits on edge of a slab, that slab edge is thickened to 8" and sits directly on the wall footing. The anchor bolts for the wall go into the slab only. There is no rebar between the wall footings and the slab that the wood wall above is sitting on. The picture...

    Sealing Documents - Personal vs Company (LLC, S-Corp, Etc)

    Hi Everyone, I have what I thought was a simple question, but turns out not as simple as I thought. I own a small engineering firm and I operate in a lot of states. I've been a sole prop for a few years for simplicity. Here's the question: If I register my business as an LLC or S-Corp in my...

    Lookout Foundation Wall - Lateral Bracing

    8-of-Trades - in my area the frost walls and the slab are, 99% of the time, never connected for single family residential projects. I could try, but I'd doubt it would get built properly!

    Lookout Foundation Wall - Lateral Bracing

    Correct - it is not braced by a diaphragm at the top. It's a stem wall that sticks up +/-4' above the basement slab on grade and has a half-height wood wall on top of it. Its called a "lookout basement" wall and it's used a ton in my area. It's code approved and used all the time on smaller...

    Lookout Foundation Wall - Lateral Bracing

    Hi Everyone, Here's a question for residential projects. Cantilevered concrete stem walls are popular in my area for lookout basements. The governing residential code says you can use propped cantilever stem walls for wall runs of up to 35' before a perpendicular wall is required to brace the...

    Old garage slab - 8" thick with steel beams cast in

    Hey everyone, Has anybody seen a garage slab from the 1950's or so with steel beams fully embedded in the slab? See the attached picture. The steel beams are 4' oc and span about 18' with a wood support post in the middle. It looks like there are 2#3 long bars in the slab running parallel to...

    Unjointed SOG Cracking Excessively

    We don't know the slump yet. I'm told it was nice weather out. I'm wondering if they put cold water on top of concrete that was 85+ degrees and the temperature differential caused some of the cracking?

    Unjointed SOG Cracking Excessively

    Hi everyone, Here's what's going on: -Recently constructed 6" thick SOG in a secondary containment facility (aka water tight concrete) -Reinforced with 0.006Ag (heavy - I know) reinforcing per ACI 360 so that movement joints aren't required (they're expensive to install and maintain - extra...

    Paint for Exterior Steel Application and Corrosion Protection

    Thanks everybody for the replies. For the case which prompted the question, the only exposed steel is a total of (3) 1/2" thick steel plates that are going to be used in flitch beams for an exterior deck with a roof over it. The primary motivation is not so much cost as it is the project...

    Paint for Exterior Steel Application and Corrosion Protection

    Hi everybody, I'm used to working in the industrial realm where galvanized steel is regular. I've been asked often about paint systems that can be used in lieu of galvanizing for low-risk applications for non-industrial applications - e.g. a steel beam used for a residential deck. Is anyone...

    What R value for moment frame with pinned base?

    Hi everybody, We are having an internal debate - what R value is appropriate for a 1-story pinned-base moment frame with several bays? (no seismic detailing - see attached image). Side 1: Moment frame provisions apply, R = 3. Side 2: Column is in single curvature and moment frame provisions...

    CMU Shaft (Non-lateral force resisting) connection to Composite Steel Podium Slab Debate

    hey Jayrod, Thanks for the responses! Our lateral system varies (conc shear walls/brace frames/moment frames). Depending what system we use, the lateral frame is either as stiff as the CMU shaft or significantly less (i.e. moment frames) Thank you both for the responses!
