i am considering using a teak beam for a roof beam of a new house. does
anyone know what the psi is for teak? Is it comparable to redwood or red oak?
I need to know this to help determine the size of the beam - thanks!
If you don't know how to find the properties data for the material you
are using, then you likely don't know how to properly size a beam. I
would suggest hiring a licensed structural engineer to do this for you.
I have a licensed structural engineer; I just need to find the info re: psi
to give to them, and they will size it. Since this is an urgent issue and my
structural engineer doesn't have time to do any research on this (a change
during construction, he has the right to take a couple of days to find it out,
but I don't have the time to wait), and he can only consult his charts that
have standard woods' info, I've taken it upon myself to just find the psi

A few observations:
An engineer does not have a "right" to take days to find information
that is readily available.
If your engineer can't find that information on the internet in five
minutes he's a dumbass.
If he takes your word for it, without double checking for himself -
which would take the same five minutes as above, he's a dumbass.
I found that in fifteen seconds.
teak + psi + species
I overestimated the time by a factor of twenty. Sorry.
If it's a change during construction, as opposed to work in the
planning stages, that takes precedence.
I'm also a little surprised that you schedule your panics. ;)
I believe that the OP is creating the problem and the engineer is
probably fed up. The OP's explanation rings hollow. What engineer
would require only the PSI? No modulus? And what PSI are we talking
about? There's more than one. I can't see an engineer not having
time to locate such readily available information. The engineer has
already designed a beam - modifying the calculations for the
substitute material wouldn't take a huge amount of time. There's
something else going on here.
Lot's of little factors point to a large PIA factor. That's the most
likely reason that the engineer is not leaping out of his chair to
assist in a last minute change. Am I reading between the lines and
very possibly wrong? Yep. I still believe it.
Please don't kid yourself. That is not sufficient information. If
your engineer accepts that first link as adequate information, he's a
dumbass. Teak is a generic name and there are a lot of different
species that fall under that rather broad classification. They all
have different properties.
Chuckle. I should have read one more post before making my last post as
I just wrote almost exactly what you wrote above. Something is fishy
here and it sounds like a wannabe engineer with just enough knowledge to
be dangerous trying to size his/her own beam.
Something is fishy here. A structural engineer experienced in timber
design would not ask you to look up data and wouldn't trust data from
other than a well-recognized source in any event. And there isn't a
single stress value (what you are calling erroneously psi) of
importance, there are several.
