AISC 1989 code supplement 1,2001 1

[csd72]

The new NY city code still refers to the 1989 code for ASD, but also refers to this supplement 1.

I cant find this anywhere. Does anyone know what it covers?

Try this.

I believe Supplement 1 is Seismic design of steel.
So, you would be better served to go to the current version, AISC 341-05.

This is the one referenced by the new 13th addition AISC [Steel] Construction Manual, aka AISC 360-06.
The AISC 360-06 is referenced from the current building code, the IBC 2006.

However, this version funnels you into LRFD.
You could also try AISC 341-02, if that is easier to use.

Best wishes!

Thanks nutte,

That is exactly what I needed.

randomizer,

This is exactly the problem, the code refers to the 1989 version, but the contractor wants to use the 13th edition for connection design. I did a comparison and most of the code is the same but compression is more conservative in the new code, and plate bending and bolts are more conservative in the old code.

I just needed this supplement to see what the new NYC code will refer to.

You should only follow what the NYC code has adopted (as a minimum). If NYC hasn't adopted the 13th Edition, using it may not be "legally" correct.

Yes, I agree, but in most places the results are exactly the same.

Only differences I have seen so far is that buckling is more conservative in the new code and plate bending and bolt shear are more conservative in the old code.

I only compared the clauses that were of relevance to my project though.
