Acceleration Indexes for Human Comfort in Tall Buildings—Peak or RMS?

Traditionally, the effect of vibration on human comfort has been evaluated using the rms value of acceleration. More recently, a widely used criteria in North America has utilized the peak value of acceleration. The differences between these two methods are examined, and the importance of making a rational selection of the appropriate motion index for future standards is emphasized. It is proposed that, until additional research in this field demonstrates otherwise, the rms value be adopted as the best available index.
