RE: 4x4 southern pine wood post design

[Subject Prev][Subject Next][Thread Prev][Thread Next]
The Wood Engineering and Construction Handbook has tables for different E',
Fc*, and Le/d values. 

The E values for Southern Pine look to be about the same or nearly the same
as Doug Fir. Since the Fc* values look to be 20% greater for Southern Pine,
I think using tables based on Doug Fir values would be conservative.

Careful,

Post (column) design may be controlled by buckling. If so, stiffness is
what you need, not strength, and I can't remember off the top of my head
which is stiffer.

Bruce,

Thanks for the offer.  I did find a table on www.wwpa.org site for posts
of
Duglas-Fur(TN9) .  Since Southern pine is stronger, I can use this table
with the assumption that my post is stronger than shown.

I seldom design in wood.  I am wondering how most people design decks
and
patios with out a load table for sawed posts???  I see a lot of 4x4
posts
around.

Ron,

I am not aware of any column capacity tables for sawn lumber (4x4 or
larger). There are some glulam tables available from APA or AITC.

I would suggest trying the WoodWorks Software. Try this link for the
demo
version.

If this does not work, email me privately and I could run the design on
my
version.

Does anyone know where I can find load tables for 4x4 treated wood post
(southern pine)??

I have found load tales for joists and beams (southernpine.org) but
can't
seem to locate allowable loads on posts(columns).  I have all the values
and
equations but don't want to run the numbers if there are tables for this
size.

Thanks.
