Desing code or standards
Desing code or standards
(OP)
Is there any desing codes (NDS, AITC) that says something about stainless steel connectors or fasteners in timber structures joints?
I am more interested about strenght (desing values) than corrosion.

RE: Desing code or standards
I don't believe any of the wood properties would vary based on the steel properties. For more information you could check with USP Structural Connectors or Simpson Strong Tie. Both of the mentioned companies publish values for high strength steel screws. I think the screws are probably grade 5 steel with a bending yield strength over 200,000 psi.

Calculating the tensile capability is not as easy as shear since the thinnest portion of the bolt is at the minor diameter of the threads (bottom of the thread “V”). So you need to know the nominal minor diameter of that particular fastener. That’s where military specification MIL-S-8879C comes in. It is titled “Screw threads, controlled radius root with increased minor diameter, general specification for”. It lists that and a lot more for almost all possible fasteners.
