    Batch processing with MDX 2023

    I never got a call back, but they did email me a "new" batch script template today. Of course that template also does not work, and it had several typos in it too lol. I already replied back to let them know it doesn't work, so I'll hold off on following up until tomorrow.

    Batch processing with MDX 2023

    Yeah, they started getting really obnoxious with the licensing rules around the time COVID hit when everyone was working remotely. We had all kinds of issues with them and had a ton of back and forth trying to reach a compromise that would allow us to use the software remotely. I believe...

    Batch processing with MDX 2023

    Yeah it seems like there's a number of issues with the new MDX. This batch processing issue might be resolved in a more recent update, but my It group can't even get the old version uninstalled ha ha.

    Batch processing with MDX 2023

    I am hoping to find someone who is familiar with MDX 2023 - in particular with batch processing. MDX had a major update some time in the recent past, going from MDXv6 to MDX Client 2023. This update involved an upgrade from the 1992-era GUI to a spiffy new 1998-era GUI. Jokes aside, there...

    Replacing subfloor and blocking composite I-joists

    It's difficult to make out some of the text in the plans because they were on microfilm, but there's definitely nothing called out in the vicinity of the railing with the pad draped over it to suggest that there's a beam or rim joist framing into the 13ft floor joist. It's not in the schedule...

    Replacing subfloor and blocking composite I-joists

    It's rough, but i put together this little sketch on my phone ha hahttps://files.engineering.com/getfile.aspx?folder=0d35803c-0152-48cd-8c77-5a14cfd299a7&file=Screenshot_20220113-080203~5.png

    Replacing subfloor and blocking composite I-joists

    I don't want to get on too much of a tangent about composite joists vs solid sawn, but my point was that with these built up joists all your strength is in the flanges. If you compromise a flange, you're screwed, whereas with solid sawn you got tons of meat to work with and the fix is simply to...

    Replacing subfloor and blocking composite I-joists

    Ok, so i got up there and tried to pull some nails. A got about a half dozen out in the worst area. The nails are ring shank, with one oddball smooth shank 16c nail. Most of the nails wouldn't budge. I was just bending them at the shank when trying to pry them out. So clearly they weren't loose...

    Replacing subfloor and blocking composite I-joists

    I'm not going to be able to look more into the subfloor until after work, but it just occurred to me that the first floor is almost definitely the same subfloor plywood and my basement is unfinished. Sure enough, the 1st floor basement sheathing is stamped APA Rated Sturd-I-Floor, 24" o-c...

    Replacing subfloor and blocking composite I-joists

    As designers, it's easy for us to overlook the real world problems that are encountered with the materials we spec, and I think these I-joists are a prime example of that. They may have made them more fire resistant and made other improvements such as pre-punched holes for utilities, but there's...

    Replacing subfloor and blocking composite I-joists

    Forgot to mention... No easy access to panel underside, though there's a small gap at the top stair. I pulled a tape on it and it measured 5/8“ or 11/16". It's 5 plys. I'm assuming this has to be 3/4" sheets, because 5/8" nominal would measure less. I could probably grab my bore scope and try...

    Replacing subfloor and blocking composite I-joists

    Ok so i think the first order of business is simply to pull the nails in the problem areas to see if it has any impact on the squeaking whatsoever. If I happen to get lucky and that be the case, then maybe I can just leave it as is despite pretty significant deflections when I walk on it? Is...

    Replacing subfloor and blocking composite I-joists

    Perhaps adding more joists isn't the best solution, but the joist span is irrelevant here. I'm not concerned about joist capacity or joist deflection. I'm concerned about subfloor deflection between joists. It deflects quite a bit when i step on it. I'm 315lbs, granted, but still it's clearly a...

    Replacing subfloor and blocking composite I-joists

    I'm a bridge engineer by profession, but I'm having a bit of an issue at my personal residence at the moment and I'm hoping to get a few questions answered. We are having carpet replaced on our second floor, and in the process the installers are screwing down the 3/4" t&g ply subfloor to...
