1.0.1 This Code is formulated with a view to implementing the "Construction Law of the People's Republic of China" and the "Law of the People's Republic of China on Protecting Against and Mitigating Earthquake Disasters", implementing the prevention-first guideline, as well as relieving the earthquake damage for buildings, avoiding human casualties and reducing economic losses after carrying out the building seismic fortification on the basis of the existing technologies and economic conditions.
1.0.2 This Code is applicable to the seismic design, seismic isolation, energy dissipation and shock absorption design of the general buildings whose seismic precaution intensity is 6, 7 and 8 and site category is Category III and Category IV in Shanghai City; the special buildings and industries shall be subject to the relevant standards and provisions under the special seismic design requirements of buildings.
Note: "seismic fortification intensity" is generally omitted in this Code, e.g. "seismic fortification intensity 6, 7 and 8" is referred to as "Intensity 6, Intensity 7 and Intensity 8".
1.0.3 As for the buildings designed according to this Code, their seismic fortification objectives include: under the impact of the frequent earthquakes below the local seismic fortification intensity, the buildings are generally free from any damage or can be in service continually without any repair; under the impact of the earthquakes equivalent to the local seismic fortification intensity, the buildings are possible to be damaged but still can be in service continually after general repair or without any repair; under the impact of the estimated rare earthquakes higher than the local seismic fortification intensity, the buildings are not collapsed or damaged badly enough to endanger the human lives.
1.0.4 Seismic design of buildings shall not only meet those specified in this Code, but also those specified in the relevant current standards of the Nation and Shanghai.
