Timber design - stress grading
Timber design - stress grading
(OP)
I have not done a lot of timber design to US codes but...is structural timber stress graded in the USA and can i verify that on a site. That is, can i pick up a piece of lumber on a project site and clearly see what stress grading it is via a grading stamp?
Same with plywood - does the US stamp plywood sheets and provide stress grades for the sheets?
My previous timber design was to Australian standards where we would see say "F14" stress grade that designates 14 MPa (2ksi) allowable bending stress.
thanks
PS - i call it timber but US engineers call it WOOD - sorry i am from the south, as in down-under south! I have always thought that wood comes from a tree, but timber comes from a mill :)

RE: Timber design - stress grading
By the way we call wood here because back in our day us engineers were responsible for the felling, milling, engineering, and constructing of all our timber structures!
Well, what did you expect after we walked three miles (one way and up hill both ways) four feet deep snow to get to school! By the time we graduated from school we were pretty hard up to top some of those earlier feats!

i guess you also mined our own ore, smelted you own steel, rolled your own sections, then had breakfast...etc
seems like the lumber and plywood i have seen is from asia and probably not rated...certainly no APA or equal stamp. I will investigate further. again, thanks.
