Re: '97 code seismic map arrived from ICBO

Yes the 1997 seismic loads are based on Ultimate loads. To get to allowable
loads, divide by 1.4.  The lads will still be significantly higher, but not
quite the heart attack you first had.

Also note the story drift requirements have been cut in half. This may severly
hamper steel moment frame buildings.
