RE: Cross-grain Compressive Strain in Timber

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I might be able to help you with a number, but I am not clear on what
the number means.  How are your example numbers determined?  

I'm also not clear on the application.

What species of wood are you talking about?

Subject: Cross-grain Compressive Strain in Timber

I'm doing some casual analysis of metal support plates bolted to the
side of, say, a built-up 2x10 beam.  If I try to use, eg, concrete
section analogy, I need to know a strain modulus for the timber (yeah, I
know timber doesn't behave like concrete).  What cross grain modulus
might I use?

 

Eg: conc = .0035, masonry = .003, steel = .002 I could see a virtual SE
= .007?  I know that ASTM tests to develop bearing stresses and lengths
invoke the concept of strain = del L/L  and I also am aware that the
value must be very variable espec with MC.


 

Again, if I use strain compatibility analysis, I have to know what value
to use for the strain modulus .

 

Thanks
