| Abstract: | In this paper, the relationships between seismic intensity and peak ground shaking are studied under no specific condition,
separately or simultaneously considering the number of building storey and site category, based on data of mean peak values
of horizontal ground motion recorded during strong earthquakes. Then, according to the statistical results, the variation
of mean peak value with intensity rating is discussed, and schemes of peak ground velocity, peak ground acceleration or response
spectrum of an designed earthquake converted from intensity rating are recommended. Finally, a methodology of converting seismic
intensity from response spectrum of design earthquake is also discussed, and the conversion scheme is recommended.
