The Conditional Mean Spectrum (CMS) is often employed to select ground motions for intensity-based assessments of tall buildings. However, the seismic demands determined by response history analyses with ground motions from a single CMS may be unconservative because multiple vibration modes often significantly influence the response of tall buildings. Existing solutions to this problem include analyzing the building with: (i) a Uniform Hazard Spectrum (UHS), (ii) multiple CMSs conditioned on… Expand
