“…of the modal frequencies resulted smaller than 2% and they decreased with the model height. These frequency changes are smaller than those reported by other authors [15][16][17]. Since the accidental eccentricity is the only source of change considered in this study, the frequency changes are small.…”

“…For example, T,,,, = 0.1N, where N is the number of stories above grade for a moment resisting frame building. These formulae are developed using the field data obtained for a number of buildings having simple geometric shapes and a fairly uniform distribution of stiffness and mass (Ellis 1980). It is uncertain whether they are applicable also to buildings with setbacks, since there are few field data on the natural periods of buildings having inajor setbacks.…”

“…Ellis (1980) surveyed publications in which both computer-based calculations and measurements of the fundamental frequencies of tall buildings were given. One problem that the author has encountered on many occasions is that it is often assumed that calculations are far more accurate than they really are.…”
