1.0.1 This national standard is formulated with a view to implement Construction Law of the People's Republic of China and Law of the People's Republic of China on Protecting Against and Mitigating Earthquake Disasters, carry out the guideline of prevention first, alleviate earthquake damage, avoid casualties and reduce economic loss after seismic design of buildings.
The Seismic fortification objective of buildings with seismic designed abiding by this code is: After hit by frequently occurred earthquakes, the buildings shall be free from damage or shall continue in service without repair; after hit by earthquake lower than local Seismic fortification intensity, the buildings might be damaged but can still be used with simple repair or without repair; after hit by rarely occurred earthquake higher than local seismic fortification intensity, the buildings shall not fall down or suffer life-threatening damages.
1.0.2 Seismic design shall be applied to buildings in the region of seismic fortification intensity higher than level 6.
1.0.3 This code is applicable to the seismic design, seismic insulation design and energy-dissipation and shock absorption design of building within regions of seismic fortification intensity of 6, 7, 8, or 9 degrees. Within regions of seismic fortification intensity higher than 9 degree, the building construction and relevant industry shall adhere to specific regulations.
Note: This code shall omit “seismic fortification intensity”, for example: seismic fortification of 6, 7, 8, 9 degrees hereinafter referred to as "6, 7, 8, 9 degrees”.
1.0.4 The seismic fortification intensity shall be examined and approved according to the jurisdiction regulated by and documents (graphs) issued by the state.
1.0.5 In general situation, seismic fortification intensity can refer to the seismic intensity in the China Seismic Motion Parameters Zoning Map (or intensity in the design basic acceleration of ground motion in this code).
1.0.6 In addition to this code, seismic design shall also conform to current compulsory standard of state.
