Stainless steel fastener and timber joints

[Raikku]

Is there any standars or research of stainless steel fasteners (nail, screws or bolts)or connectors in mechanical timber joints?

I am also interested in determination of yield moment of dowel type fasteners (nails) made by stainless steel.
What kind of test metods and is there any results.

These values are needed for design joints by yield model (Johansen, Larsen)

Maybe try NIDI

http://www.nidi.org/

they have a couple of publications on Stainless Steel fasteners.

Why are you considering stainless steel fasteners that much differently the standard connections. I would think you can use the ratio of material strenght for shear and bending values and the same pull out strength.

I am interested in research that could I make use of stainless steel better ultimate stress than standard ones.

Stainless steel stress-strain curvature is different than so call "normal steel".

Since there are so many SS and heat treatments/cold working available, do you have some idea of which ones you want?

I think austenic steel such as ASTM (AISI) 304, 321, 316 (L), 316Ti could be useful. Cold-formed or annealing would be working method for SS.
