    Structure Magazine old issues

    If there's a specific issue or article you're after, I suggest you be specific.

    Anchoring scissor car hoist/lift

    I mean the ANCHOR manufacturer's installation instructions.

    IEBC Allowable 5% Gravity Increase on Total Load or Load Type?

    I dunno, you asked for a scenario and I came up with it without giving it the full analytical. If somebody figures out when the wording changed, I could dredge for the code change proposal, but I'm not sure anybody actually wants that. I don't have a full collection and IEBC was for a time not...

    Digital Seal and Signature

    Yeah, it's been discussed before. My recall of that had to do with some odd requirements in Florida as the most recent iteration of this conversation. Most states there's a difference between an electronic signature, and a digital signature (which is semi-encrypted). Once upon a time I had a...

    Footing uplift safety factor

    Nuts I was going to make some smart comment about buoyancy forces being in the code and I struck out. Maybe that's in ACI 350 which probably doesn't apply here as it doesn't scream environmental engineering concrete structures. I believe other standard like, say, API (American Petroleum...

    ASR

    Alkali-Silica Reaction? It would have the potential to penetrate and if it's on the top surface, likely the whole batch has the problem, so it would progress. Isn't that moisture driven? I'd have a tough time convincing myself that moisture could somehow be precluded on a foundation, because...

    Ponding Load

    Just when I think I'm out, they pull me back in. @chorus, You mean Emin? That's an interesting question, but my familiarity with Emin is it's more of a computational/tabulated artifice to unify LRFD/ASD design in wood to a single design equation (for bending and compression) rather than...

    Beam Reinforcement Calculation

    Source: Stack exchange. Where the section changes, shear jumps. If this were a plate girder you'd be welding the top and bottom plates to the web to transfer that shear, it's no different than the case at hand, it's just the section is getting thicker in the middle which is atypical. If it...

    Ponding Load

    The what, 1996 LRFD for wood construction has a procedure for ponding on wood. ASCE 16 wasn't it?

    IEBC Allowable 5% Gravity Increase on Total Load or Load Type?

    As a side note, it looks like the actual text hasn't changed between 2018 and 2024. Here's the 2024 for reference, I notice the bit about current IBC in there now, I was working off brute recall. Source: 2018-2024 IEBC What I'm getting at is the basic question was about what the 5% applied...

    IEBC Allowable 5% Gravity Increase on Total Load or Load Type?

    I think that's thematically correct but potentially overkill. If it's over the 5% you're required to analyze it, isn't that the wording? That isn't exactly binding it to the new code, in terms of language? The one issue I could see is there have been a LOT of changes in punching shear in...

    Can a R/C moment frame ever go pass 1% interstory drift without collapsing (NLTHA)

    Non-linear time history analysis? Starting to feel like an FAQ for all the user-created acronyms is needed. My Captain Crunch decoder ring broke a while back as it was non-UV resistant plastic.

    Good idea. I updated the FAQ to refer folks here. It may take a bit for approval to come through.

    Beam Reinforcement Calculation

    XR250, Yeah, that looks like the first edition, all I can find online as to traces is an arabic translation from 1981, so probably. Abebooks normally has this information but not for this book. Yeah, I know, not the question being asked, but.... Fundamentally this is a built-up shape. Since...

    Ponding Load

    Since the OP hasn't responded, I think they got what they wanted and I don't need to argue with you, Dave. The excerpt I posted did address your comment because you claimed there's a distinction between a blocked drain analysis and a ponding analysis, and intrinsic in the rain load case...

    Beam Reinforcement Calculation

    Has Koot gotten into this one yet? I haven't read the four pages yet.

    Slideruleera.net Successor

    I can modify the FAQ to suggest people contact you with files they find? or if you'd rather, I can just pull down the FAQ entry after you copy it, and you can post and curate it going forward.

    Anchoring scissor car hoist/lift

    Follow the manufacturer's installation instructions, i.e. use the proper tools which you may have to rent from somebody for the more esoteric anchors. Epoxy you want to properly brush out and blow out the holes, ensure that it's dry, and follow the mixing ratios, setting time, and so forth...

    How to create new FAQ

    Is there any way to SORT these, I have some fairly large sets of FAQs (i.e. in the AISC forum) and they are no longer sorting by the leading year in the FAQ entry (i.e. 1965 doesn't show up before 1970, and so forth).
