the glass fin is slender, but what forces does it really withstand?
the fin is only braced on on edge, the other edge is free to warp.
my guess would be, if there was a seriously big and wet pile of snow on the roof, and you ran a stringline down the inner edge of one of those fins, the glass...
i imagine the actual strucutral post will be a 6x6 or 8x8 timber up the centre
then you will have secondary non-structural framing surounding it to build out the geometry
apply the veneer back to the secondary framing
ideally the "interior" build up should freely ventilate so as to avoid rot
@Greenalleycat
im sorry mate
you are talking about how "highly ductile" plasterboard/gib is
but then in all your descriptions of it, you are describing how poor the ductility is?
the plasterboard fails via brittle failure of the board material (the crumbling of the plaster), immediately...
yes, i love Australia, but way too uptight, too many rules and fines.
my mate went to queensland for holiday and got $6000 worth of speeding tickets in the mail upon his return!
kiwis love to gloat that they are far better tradies than the australians... but to be honest, i thought trades in...
yes you are reading it right
yes, it is a little bit insane.
because you effectively cant get any water in that opening, because it has 0 weather protection, they push the windows right outside of the opening, so the glass is proud of the cladding.
the craziest part though and the completion of...
i am in NZ now but used to practice in Canada
last i was in canada, maybe 10 years ago, i think the standard was CSA O-86? had provisions in there that 20% of the lateral force resisting system could be provided by the "GIB" or drywall as we called it. the remaining 80% had to be provided by...
There was an engineer from my grad class (civil), with a bachelors only, in canada.
he was hell bent on California. he got a local job after graduating, only ended up there for a very short time (a few months), then i guess searched pretty hard and did the TN thing.
haven't caught up with him...
I reckon this is a bit harsh, and unfair. Do you have your own business, CWB1?
I know all sorts of engineers in my business. Guys with 25+ years of experience that are absolute clowns, and young engineers with 5 years experience that have picked up the trade very fast, and totally outclass...
I've often wished I had moved to America. I love the place. But due to the trajectory of my life, i will likely only ever go as a visitor.
Reading things like this though, reminds me of the flaws of the great nation. Reading between the lines here, OP is looking for somebody to sue.
The...
I went out on my own at 31 as well.
I didnt have a kid at the time, but do have one now. I probably wouldn't have made the leap with a kid, it would have felt way too risky. Hell, i had so many sleepless nights, even though in hindsight, the outcome of failure would have been totally fine.
I'm...
looks like a mildly dodgy deck to me.
probably wont collapse, but its not an "engineered" solution.
this is what i always tell clients in situations when im getting leaned on to sign something off that is generally distasteful.
"listen - its not so dangerous that i will call the city...
@CWB1
From my general understanding,
people in general in Australia are very well paid, compared to the rest of the developed world.
tradesmen in Australia are very handsomely paid, compared to the rest of the developed world.
engineers in Australia, are not all that well paid, compared to the...
hi 3DDave yes this method is the simplest.
Though is appropriate for "cantilevered" members with a torque on the end, rather than torque on an element with both ends fixed.
a member with both ends fixed will rotate much less - this phenomenon seems to have a range of proposed equations that...
Thanks everyone for your replies
i've gone through a handful of resources - Rourkes, AISC, some miscellaneous papers... it appears there is no standard method...
ive got a few different spreadsheets set up and i will run an FEA and see how everything compares.
thanks for your time and the...
I've got a weird one that i know i could have solved in my university days, but has me scratching my head these days.
I have a column, fully fixed at both ends, very tall (~9metres)
It is subject to near nil compressive forces, or bending forces (no WL2/8 business). but it is very tall...
not ideal
especially if the pipe expands/contracts along its length, could impart forces onto the brickwork.
the brick
if there is any way to fix through the brick to the structural wall behind?
or - from your image it looks like you are in there early.
could you clamp something/fit...
@Enable is on the money.
What determines rates?
of course market forces are a big factor. location, supply/demand.
but within a particular market, i find the two biggest drivers of pricing are:
1. Specialization.
2. Level of service.
If you do the exact same thing as 50 other firms in the...
Who is hopeless?
billing rates really depends on specialty/industry
building construction being quite a lower paying industry, generally, though maybe one of the higher paying industries in NZ (due to our lack of any other big resource economy)
I have found this paper - which describes the chemical process quite well:
