For the purpose of this study, three buildings were designed including a 4-storey, a 10-storey, and a 16-storey building, that can be considered typical of low, intermediate, and high rise buildings respectively. The buildings were designed for the city of Vancouver, Canada, which is in a high seismic region. A set of 40 recorded accelerograms representative of seismic motions in the Vancouver region were selected for use in the seismic analysis. Each building was subjected to a series of seismic excitations producing responses that ranged from elastic to significant inelastic responses. The free vibrations of the buildings, after the end of each excitation motion, were analyzed to determine the postexcitation fundamental (i.e., the first mode) periods. The computed periods were statistically analyzed to determine the relationship between the elongation of the fundamental period and the intensity level of the seismic excitation.
