Interior Seel Stair Seismic Design
(OP)
I have a steel stair that I am providing structural calculations that is located in Virginia Beach, Virginia. The performance specifications require a seismic analysis of the steel stair framing. It appears that the seismic design category is B based on the 2003 NEHRP maps and the IBC/ASCE. Could someone please inform me regarding the correct way to determine seismic loads under a seismic event.
Thank You,
Val Courtney, P.E.

I've done some indoor self-supporting steel stairs and mezzanines per IBC 2003 1617.4 -which refers to Equivalent Lateral Force procedure per ASCE 7 - Section 9.5.5. (2002 edition)
Regarding the use of nonbuilding provisions - can anyone comment? I haven't seen references in the code sections to self supporting stairs/mezzanines being considered nonbuilding structures.
