    Index for 12 page calculations?

    Yes - they only had the requirement for the same place on plans, on calcs I can't do that as it's output from software and well it's just not possible to always have in the same place. I should note - they no longer ask for this on calcs.

    Index for 12 page calculations?

    Wait till you get a plan reviewer that wants a seal on every page; that was a quick no. Or the plan reviewer that wanted a blank spot on every page for the city stamp... I happily gave them that and requested a copy with their stamp on every page, even printed extra pages for this one...

    External anchorage of reinforcement - is this feasible?

    I came across these at a structural engineers convention recently, they looked interesting and may work for what you need. https://pourstrip0.com/

    Ultimate vs. Allowable Passive Pressure - which to use with a safety factor

    Safety factors are required for retaining walls and use ASD combinations which uses allowable pressures, therefore the building official is correct, ultimate pressures need to be converted to allowable and then the safety factor applies on top of that. I don't know what value to use for ultimate...

    Crazy cantilevered steel deck

    I'm with the others here, the anchors look like the weak point. I would have at least had heavy hex headed anchors for anything with reasonable tension or moment. J-bolts aren't that great in tension. A single 3/4" dia. J bolt with 12" embed with tension only is going to give you about 3700 lbs...

    Roof top Solar Panels

    Going from a flat roof to many rows of open frames in a sawtooth layout will most definitely change roof uplift, however as you have said, probably not a big concern for uplift itself, the issue is in the fact that the OP said it's a ballasted system, which means no physical attachment and they...

    Everything we do out West requires calculations.

    Index for 12 page calculations?

    Sounds to me like they are just going through a list, looking for something to comment on. I would be pissed I had to waste my time, on the flip side, it's easy to do for 12 pages. I have turned in 5000+ page calculations before without an index (whoops) and had no issue and rarely include an...

    Roof top Solar Panels

    As I have done many ballast and non-ballast solar system designs many years ago, including roof checks, I suggest you get the final ballast weights and that they use a company that has a ballast system that relies on wind tunnel testing as many of the larger outfits that make racking do. There...

    Roof top Solar Panels

    What orientation are the solar panels? Flat to the roof, sloped to the roof? What are your concerns, solar panels are very light, especially compared to concrete, could the IEBC be used by chance to show you are barely increasing the stresses?

    Unconstrained Bollard Design Check

    Another idea to consider: Isolated pole factor to increase lateral pressure.

    RISA3D help

    A few thoughts on this: 1. Lock the Y rotation as a reaction on each pinned base, you will then see the reaction is 0, sometimes this is just an annoyance that comes up in RISA 3D. 2. Column M7 is set to pin at the top, remove that as the beams framing in are set to pins this is why N8 wants to...

    Deep epoxy embedment in foundation wall

    I have always had an issue with this approach because it seems to me that the old Chapter D checks still apply for side face blowout etc. However I could maybe buy it if you have equal area adjacent reinforcing to lap too that drags down to the foundation, in which case you are really a lap...

    Replacing Portion of Slab-On-Grade of Pre-Fab Metal Frame Building

    This sound like you are creating a tie beam but using the slab reinforcing in lieu of a separate beam below the slab, in which case it's a constant tension member and I believe per code requires mech or welded splices not allowing for lapped.

    Shear strength of fastener in plywood

    In case you missed it, E830 that @Ron247 shared above has what you are looking for.

    Replacing Portion of Slab-On-Grade of Pre-Fab Metal Frame Building

    I don't follow your thought here, are these dowels across a joint only, if so the way I read the code is you would have a constant tension member and therefore require continuous reinforcing or mechanical/welded splices in the zone in which you intend to grade for friction resistance due to slab...

    Link to the Vulcraft Table for allowable roofdeck overhang/cantilever

    Never seen one, always just hand calculated it myself.

    Reinforce masonry wall to deal with settlement risk

    Maybe some sort of foam or grout injection could be used to stabilize the soils a bit better, it's often use for jacking up foundations and roadways where soils have settled.

    Cold Formed Steel naming

    SSMA when I use SSMA shapes, ie wall studs and sometimes floor or roof framing, AISI when I use members similar to PEMB's, ie Z and CEE shapes for things like purlins and wall girts. I haven't encountered any challenges or confusion thus far from contractors, other than some like to list gages...
