You’re more generous than I am if you think they’ll learn much from this. They immediately blamed “atmospheric phenomena” and “sabotage”—the same deflections communists used when their control of agriculture led to famine. Do you seriously expect them to admit that forcing too much unstable...
The difference between mandatory and recommended serviceability limits is an interesting one.
Australian codes usually offer “suggested” or “recommended” serviceability limits, which everyone tries to meet, and often exceed, because the minimums often aren’t enough to stop your phone from...
Sounds familar lol. There is wisdom in this. For possibly contentious matters, get it in writing whether the client wants the code minimum, or something better.
These attribution studies are some of the ugliest examples of cargo cult science we’ve seen in years. It’s rare to see "science" so nakedly engineered around a pre-chosen conclusion. It’s right there in the name: attribution. The whole purpose is to attribute events to climate change, whether...
That’s how it works in practice when countries go metric. Some things are too hard to start from scratch.
And things like plywood, we still have 2440 sheets of ply. The old imperial system is still there in many ways.
It’s not as difficult as you might think. Where a direct swap is easy, you just use the exact metric equivalent, for example, a 6” slab becomes a 150 mm slab.
Using metric materials on old imperial buildings isn’t a big deal either. We retrofit old imperial structures with new metric materials...
You’re reading too much into the wording. Calling LRFD a “dressed-up ASD” and a “technical refinement” is just two ways of saying the same thing: that LRFD didn’t create new safety benchmarks, it simply inherited and tweaked the ones already established by ASD. That’s why the LRFD factors are...
If you read those documents properly, you’ll see that LRFD was pegged to the reliability established by ASD. That’s why the LRFD reliability index curve closely follows the ASD curve and intersects it near the middle, because LRFD was deliberately calibrated to match ASD for normal design work...
I think there’s been a misunderstanding of what I’m saying.
I’m not comparing ASD to LRFD as if it’s akin to just changing a sign from “10 miles to Shelbyville” to “10 kilometres” without moving the sign.
What I’m saying is this: switching from ASD to LRFD is like changing that sign from “10...
