Design seismic force is amplified at higher elevations in a building. Best way to describe it is "whipping effect". If your building is, say, five stories with roof height at 60 feet and you have a wall mount unit at 5 feet above seismic base, your hr = 60 feet and hx = 5 feet....

The method of determining the seismic design response spectrum of the Uniform Building Code 1997 u-sing C a and C v in the United States was introduced. If the site meets the 4 conditions:(1)The building is locatedin seismic fortification zone 4;(2)The fault is active fault;(3)Faults ...
The transition from the Uniform Building Code (UBC-97) to the International Building Code (IBC-21) marked a major shift in the definition of seismic hazard. The term “seismic hazard” in the form of peak ground acceleration (PGA) is replaced by spectral acceleration. This paper investigates ...
