What pitfalls using BS EN 1993-1-1 with US shapes and mat'l?
(OP)
We're looking at bidding a job that the owner has specified BS EN 1993 for steel design even though the location is in Africa (go figure). We will be using US shapes and material. We use STAAD.Pro for our steel design and right away I noticed that you cannot specify yield strength. You have to specify steel grade (S235 to S460) and the program will plug in the yield strength. So for 50 ksi steel I guess we would tell STAAD it is S355.
We sprinkle some stainless steel members throughout our structure with a yield strength of 30 ksi. I see nothing that goes this low in the European steel grades. One work around would be to call it S235 and not go over a unity check of about 0.85. I haven't completely thought this throuhg yet. Anybody have a better idea?
What other things should I be looking out for? We haven't bought any of the BS EN 1993 codes yet so I'm kinda fumbling around in the dark. Yeah, yeah, I know, "Buy the codes!" but before we do I want to make sure mixing European codes with U.S. shapes is tenable.

I'm not a structural engineer, but I know that the 'Blue Book' is/was the bible for steel section properties. Below are a couple of links to it. (TATA was Corus was British Steel...).

I believe staad has a comprehensive sections library which will allow you to model us sections - but I will check tomorrow!
There are a few other resources you could use before investing in EC3. Access steel is a good web site with lots of worked examples you can access for free after registration. There are also a number of Tata publications available free of charge on the www.

US shapes / sections are not common in Africa; check with your supplier before you proceed with detailed design.

You'll find additional information regarding stainless steel grades.

This link contains a full list of free bibliography (design examples, case studies, design guides) for structural steel design according to Eurocodes! I am sure you will find it useful!
