Up to now, 11 volumes of Report on Strong Earthquake Motion Records and 1 volume of Report
of Long-period Response Spectrum have been published by EEM. In addition, China institute of
water resources and hydropower research has edited and published 1 volume of Important Data
on Strong Motion and Analysis in China Hydraulic Structures, including important strong
motion records that recorded at Xinfengjiang reservoir dam, Huangbizhuang reservoir dam and
so on.
Strong motion records of China have been used in draw up the various design codes of structures,
seismic ground motion parameter zonation map, probabilistic seismic hazard analysis,
earthquake safety evaluation, seismic design of structures, studies on characteristics of
earthquake ground motion and attenuation lows of ground motion. For example, the
accelerograms recorded at Qianan station during the Tangshan aftershock of August 31,
1976(m=5.8) and the accelerograms recorded at Tianjing hospital station during the Ninghe
earthquake of November 15, 1976(m=7.1) are used usually as the input seismic wave in
vibrating table experiment and seismic calculation of structures. Figure 5 to 8 is typical strong
motion records of Mainland China.
