Engineering Construction Standard Full-text Information System
1 General
1.0.1 This code is formulated to implement the earthquake work policy of prevention first, reduce the degree of earthquake damage to structures, avoid casualties and reduce economic losses. 1.0.2 Structures designed for seismic resistance in accordance with this code will generally not be damaged or can continue to be used without repair when they are affected by earthquakes with a seismic intensity lower than the design intensity of the region; they may be damaged when they are affected by earthquakes with a design intensity of the region, but can continue to be used after general repairs or without repairs; when they are affected by an earthquake with a design intensity higher than one degree in the region, they will not collapse or suffer serious damage that endangers life or causes major economic losses. 1.0.3 This code applies to the seismic design of structures in areas with a seismic design intensity of 6 to 9 degrees.
Seismic design of structures in areas with a design intensity of 10 degrees and in industries with special requirements should be specially studied and implemented in accordance with relevant regulations. 1.0.4 The seismic fortification intensity can adopt the basic earthquake intensity specified in the current "China Seismic Intensity Zoning Map"; for areas or factories and mines that have undergone seismic fortification zoning, seismic design can be carried out according to the fortification intensity or seismic design ground motion parameters confirmed by the approved seismic fortification zoning.
5 Structures should be divided into the following four categories according to their importance: 1.0.5
Class A structures - structures that are particularly important or have special requirements, and earthquake damage will lead to extremely serious consequences;
Class B structures - important structures, and earthquake damage will lead to serious consequences such as large number of casualties, serious secondary disasters, and long-term interruption of production in important factories and mines; Class C structures - structures other than Class A, B, and D structures Class C structures - minor structures, which are not likely to cause casualties and large economic losses in the event of earthquake damage.
1.0.6 The seismic design of various structures shall meet the following requirements: Engineering Construction Standard Full-text Information System
Engineering Construction Standard Full-text Information System
1 The seismic action of Class A structures shall be calculated according to the seismic design ground motion parameters specially studied; the seismic action of other types of structures shall be calculated according to the fortification intensity of the region, but when the fortification intensity is 6 degrees, the seismic action calculation may not be performed unless otherwise specified in this code.
1.0.6.2 Special seismic measures shall be taken for Class A structures; seismic measures may be taken for Class B structures according to the fortification intensity increased by one degree, but the fortification intensity may be appropriately increased when it is 9 degrees; seismic measures shall be taken for Class C structures according to the fortification intensity; seismic measures may be taken for Class D structures according to the fortification intensity reduced by one degree, but the fortification intensity should not be reduced when it is 6 degrees. Note: ① This code abbreviates "design intensity" as "intensity" and "intensity of 6, 7, 8, and 9" as "6, 7, 8, and 9". ② The provisions of this code on taking seismic measures to reduce the intensity by one degree shall only be reduced once when there are multiple favorable factors.
7 This code is compiled in accordance with the provisions of the current national standard "Unified Standard for Reliability Design of Engineering Structures" and the current national standard "Basic Terms and Common Symbols for Engineering Structure Design".
In addition to implementing this code, the seismic design of structures shall also comply with the provisions of the current relevant national standards.
