AbstractA method is presented for determining overturning moments in single-storey structures with flexible foundations subjected to earthquakes. By means of a transformation of frequency response curves, an equivalent single-degree-of-freedom model is derived to represent the overturning moment of the structure. This model is characterized by the fundamental resonance frequency of the interaction structure and an equivalent damping ratio. Response calculations are presented and response spectrum techniques are described for finding maximum overturning moments. The results from a parameter study show that structures with a height-to-base width ratio greater than 1.0 generally have larger overturning moments than fixed-based structures with the same resonance frequency and interstorey damping.
