    France 95% renewable last year

    That's reasonable in my book.... My biggest pet peeve is how many "environmentalists" who believe CO2 emissions are an existential crisis somehow want to do away with nuclear power. Sometimes they hate hydro power too. I'm convinced it's just that they've been brainwashed to believe things...

    Wood Diaphragms in FEA Models

    The NDS's Special Design Provisions for Wind and Seismic (SDPWS) has a section on how to modify G based on nail spacing and such to get reasonable good elastic behavior for design. This would be for the semi-rigid (or semi-flexible) modeling approach. Of course, lots of people will choose the...

    Composite Residential Joists

    To me, it sounds like the type of framing to use on a deck, or patio cover. My patio cover was made with rough sawn lumber..... The termites love it!! If I were to replace it, I would certainly consider a product like this. There is no load (other than self weight) and maybe some "sun shade"...

    Determining Moment from different strains of column interaction

    By default, I would use the centroid of the column as the basis for my force calculations. I'm not sure it matters all that much if there isn't any axial load in the column. If there is axial load in the column then you should probably use the centroid.... Since this corresponds to where the...

    Unsupported Residential Foundation Design Methodology

    How are you analyzing the wall? a) You could model it as a cantilever retaining wall that is free at the top and fixed as a base. That base footing would need to resist significant moment. b) You could analyze it as a pinned-fixed wall where the top diaphragm or slab restrains the top and there...

    Considering leaving structural engineering behind as a career.

    Huh? What's the deal with this last post by "Stanleyshum19". He acts like he's responding to someone named Stanley. But, that's not the original poster. Is this someone trolling our site? Maybe trying to advertise their own software or something? Very weird. Though it does seem like it...

    Cross-grain bending with bounded diaphragm

    Technically, I think you do see some cross grain bending. I just don't think this is the type of configuration the code is concerned about. a) The nailer on the diaphragm side of the HSS would experience cross grain bending as the diaphragm moves away from the HSS. b) The nailer on the far...

    Things are Starting to Heat Up - Part XIV

    For what it's worth, here is an MSN article suggesting that there are other things that are helping to reduce global warming that are not being accounted for...

    Things are Starting to Heat Up - Part XIV

    38 Trillion per year..... based on a 15% per year inflation between now an then? LOL Regardless, we'll all do a little dance when this is proven to be 100% wrong. FWIW, what's the alternative? They'd like us to spend trillions and trillions NOW to reduce our CO2 footprint while the...

    Foundation Wall Mess

    Do you have drawings that show what kind of reinforcement is in that way? Also, do you know when the house was built? The construction looks a little sloppy to me. I'd want to know who built the house and if there might be something in the drawings to explain the behavior we're seeing.

    Gyp Board Shear Walls for Multi Story Apartment Building

    Ugh. I personally hate the idea of relying on Gyp board for lateral resistance. The only time I've seen this done is when someone had an existing structure and they wanted to justify why should be allowed to do a renovation even though the lateral system didn't calc out.... Heck, I believe the...

    California Dreaming No More

    I've been seeing a god amount about this recently.... I haven't really read much about it. But, I've seen headlines related to preventing the spread of bird flu. I'm not sure if it's exclusively in CA or not. FWIW, California has regulations that essentially require cage free hens if you want...

    California Dreaming No More

    Dik - What I'm getting at is the "alarmists" tend to blame everything on global warming without being able to cite any data to back up their opinions. This is intellectually poor reasoning. And, I personally expect more out of you. It's like when the DEI / social justice / neo-Marxist...

    California Dreaming No More

    This is one of the most passive aggressive things you've ever posted. All you give is silly platitudes about how anything and everything COULD be related to global warming. You probably don't understand CA weather at all. That's okay, I tried to explain how we had last winter was very wet...

    Bowing basement wall

    I would think this would be feasible.... with shear studs / dowels into the existing wall for connectivity. The biggest problem with this is how you're going to do the foundation for the new wall..... FWIW, I've learned a lot from this thread already. I didn't realize that the Carbon Fiber...

    California Dreaming No More

    I fail to understand how these wild fires have any relationship to Global Warming. The way I see it, Southern California is always either in a drought, has just come out of a drought or is about to go into one. It's always been dry here. Period. The difference is urban / suburban sprawl...

    Structural Slab Supported at Corners

    I respectfully suggest that this may be due to Mxy (or warping) moments. I tend to think of this as a tendency to warp or distort the plate rather than to bend it. Since I'm more of a steel guy, I tend to related it to the Torsional Warping of I shaped beams.

    Things are Starting to Heat Up - Part XIV

    Somethings that I was thinking about recently: a) Greta Thunberg gave her "how dare you" speech at the UN approximately 5 years ago. What has changed since then? Are ecosystems genuinely collapsing? Not really. All the doom and destruction predictions haven't come true at all. At least not in...

    Things are Starting to Heat Up - Part XIV

    That is a funny / pithy comment for sure. I don't think newspapers have been very "factual" for a long time. So much so that they're in a death spiral lashing out at new media because they lost control over the political narrative in the country.... Basically because they've completely lost the...

    Artificial Intelligence in Structural Engineering

    Exactly. That's what it's best at. Or, at least that's the easiest thing to teach AI to do. Variations on this will likely be the primary driver for the use of AI for the time being. You have to remember, the only thing AI can do is what you teach it. If you teach it things that aren't...
