Hey All,
I had an interesting change-order the other day due to stair framing in a moment frame building. Apparently the drift was more than expected (although still a drift ratio under 0.0015) This had me thinking on what information is most critical for those who do stair design. In this case it was a differed submittal on a 6 story steel MF building.
Would stair design be just as sensitive to seismic parameters as far as the bracing required? are there any good references for preferred stair attachment methods, or differed submittal practices when it comes to stairs? Is handling drift particularly costly that, for example, stairs in a BRB based building would be a little cheaper than a MF building?
Thanks
