Very Simple Seismic Question
(OP)
Calculating Seismic Base Shear using the Simplified analysis procedure in IBC chapter 16:
I'm absolutely sure I'm right on this, but I have no one in this office to verify me. When I pull Ss and S1 (mapped spectral accelerations) off of the contour lines on these maps of the U.S. they are given in %g. For example, for Oregon coastline its 125% - 150%. When I plug these values into equation 16-38, 16-39 -> Sms = FaSs I'll plug in 1.25 or 1.5, correct?
Thanks

Thanks! I've been looking for a book with seismic force calculation examples... I'm on Amazon looking for a used one now.

Look into the 2000 IBC Structural/Seismic Design Manual - Volume 1. It should have many examples including seismic coefficient example. I do not have this book but I have all three volumes based on 1997 UBC. Therefore, I assumed similar. I'm not sure if they published one for 2003 IBC. You may contact ICC about that. Good luck.
