1.0.1 This code is formulated with a view to implementing the relevant laws and regulations on construction engineering and earthquake prevention and disaster reduction, carrying out the policy of "prevention first", as well as alleviating the seismic damage of buildings, avoiding casualties and reducing economic loss through earthquake protection of buildings.
As for the buildings adopting seismic design according to this code, the basic seismic precautionary objectives are as follows: under the frequent earthquake action with intensity being less than the local seismic precautionary intensity, the buildings with major structure undamaged or requiring no repair may continue to serve; under the earthquake action with intensity being equivalent to the local seismic precautionary intensity, the buildings with possible damage may continue to serve with common repair; under the rare earthquake action with intensity being larger than the local seismic precautionary intensity, the buildings shall not collapse or shall be free from such severe damage that may endanger human lives. If the buildings with special requirements in functions or other aspects are adopted with the seismic performance design, more concrete and higher seismic precautionary objectives shall be established.
1.0.2 All the buildings situated on zones of seismic precautionary intensity 6 or above must be carried out with seismic design.
1.0.3 This code is applicable to the seismic design and the isolation and energy dissipation design of the buildings suited on zones of seismic precautionary intensity 6, 7, 8 and 9.And the seismic performance design of buildings may be adopted with the basic methods specified in this code.
As for the buildings suited on zones where the seismic precautionary intensity is above Intensity 9 and the industrial buildings for special purpose, their seismic design shall be carried out according to the relevant special provisions.
Note: For the purposes of this code, "seismic precautionary intensity 6, 7, 8 and 9" hereinafter is referred to "Intensity 6, 7, 8 and 9".
1.0.4 The seismic precautionary intensity must be determined in accordance with the documents (drawings) examined, approved and issued by the authorities appointed by the State.
1.0.5 Generally, the seismic precautionary intensity of buildings shall be adopted with the basic seismic intensity (the intensity values corresponding to the design basic acceleration of ground motion value in this code) determined according to the "Seismic Ground Motion Parameter Zonation Map of China".
1.0.6 In addition to the requirements of this code, the seismic design of buildings also shall comply with those specified in the relevant current standards of the State.
