3 Terminologies and Definitions
For the purposes of this document, the following terminologies and definitions apply.
3.1
Seismic ground motion
The vibration of ground surface and near surface medium caused by earthquake.
3.2
Seismic ground motion parameters
The seismic ground motion physical parameters characterizing the seismic fortification requirements, which include seismic peak ground acceleration and characteristic period of the acceleration response spectrum, etc.
3.3
Seismic ground motion parameter zonation
The zoning of land into zones of different seismic fortification requirements according to seismic ground motion parameters.
3.4
Seismic peak ground acceleration
The index characterizing the intensity level of earthquake action and it corresponds to the horizontal acceleration of the maximum value of standardized acceleration response spectrum of seismic ground motion.
3.5
Characteristic period of the acceleration response spectrum
The period value corresponding by the drop point of standardized acceleration response spectrum curve of seismic ground motion.
