This standard is applicable to the seismic fortification of new, rebuilt and expanded general construction projects, as well as the preparation of social and economic development and land use planning. 2 Definitions
This standard adopts the following definitions.
2.1 Seismic ground motion parameter zonation The country is divided into areas with different seismic fortification requirements based on the seismic peak acceleration and the characteristic period of the seismic response spectrum. 2.2 Seismic peak ground acceleration The horizontal acceleration corresponding to the maximum value of the seismic response spectrum. 2.3 Characteristic period of the seismic response spectrum The period at which the seismic acceleration response spectrum begins to decrease. 2.4 Probability of exceedance The probability that a site may encounter a seismic parameter value greater than or equal to a given value. 2. 5 Requirements for seismic resistance; requirement for fortification against earth-quake
The criteria for construction projects to resist earthquake damage and the earthquake intensity or seismic parameters used in seismic design at a certain risk level. 3 Technical elements
3.1 The scale of "China's Earthquake Peak Acceleration Zoning Map" and "China's Earthquake Response Spectrum Characteristic Period Zoning Map" is 1:4 million. 3.2 The defense level of "China's Earthquake Peak Acceleration Zoning Map" and "China's Earthquake Response Spectrum Characteristic Period Zoning Map" is a 50-year exceedance probability of 10%.
3.3 The site conditions of "China's Earthquake Peak Acceleration Zoning Map" and "China's Earthquake Response Spectrum Characteristic Period Zoning Map" are flat and stable general (medium hard) sites.
3.4 ​​"Earthquake Response Spectrum Characteristic Period Adjustment Table" adopts four types of site division. 4 Use regulations
4.1 The seismic design of new, expanded and rebuilt general construction projects and the seismic appraisal and reinforcement of existing general construction projects must be carried out in accordance with the seismic defense requirements specified in this standard.

Explanation on the transition from basic earthquake intensity to earthquake parametersSoft
This standard directly adopts earthquake parameters (earth motion peak acceleration and characteristic period of earthquake response spectrum) and no longer adopts basic earthquake intensity. The current relevant technical standards involving the concept of basic earthquake intensity should be gradually revised. Before the technical standards are revised (including partial revision), they can be determined by referring to the following methods: a) The earthquake parameters provided by this standard are directly used for earthquake prevention and disaster reduction calculations; b) When foundation treatment, structural measures or other earthquake prevention and disaster reduction measures are involved, the basic earthquake intensity value can be obtained from this standard by looking up the peak acceleration of the earthquake motion and determined according to Table D1, or it can be divided more finely as needed.
