Classification Standards for Seismic Fortification of Chemical Buildings and Structures HG/T 20665 - 1999

In the seismic design of engineering, the seismic fortification category of the building and structure should be determined first according to its importance, and different seismic fortification standards should be adopted according to different categories to reduce ground hazards and use construction funds reasonably.
The national standard "Standard for Classification of Seismic Fortification of Buildings" (GB50223-95) was issued in 1995, and Article 7.0.5 of the standard stipulates the seismic fortification categories of chemical and petrochemical production buildings: "The buildings of major production equipment and their control systems of large and medium-sized enterprises, the buildings of large rooms and their control systems where highly toxic, flammable and explosive substances are produced, and the power system buildings and fire garages of large and medium-sized enterprises are classified as Class B. In addition, Article 1.0.3 of the standard also stipulates: "The seismic fortification categories of buildings with special requirements and industries not listed in this standard should be implemented in accordance with the special regulations of the relevant departments. ”
Chemical buildings and structures will suffer social impacts and economic losses from secondary disasters such as fire, explosion, toxic gas leakage, and radiation in earthquake disasters. Therefore, the formulation of the "Classification Standard for Seismic Fortification Grades of Chemical Buildings and Structures" is not only necessary but also of great significance. It can not only guide the seismic design of chemical civil engineering, but also has a certain reference role in the seismic design of processes, equipment, electrical, public engineering and other specialties. Because this standard covers a wide range, it is a highly policy-oriented standard and is closely related to the leading chemical process profession. Therefore, in the preparation of this standard, we not only solicited the opinions of nearly 30 chemical design units, but also asked many process professional designers to review and deliberate repeatedly to make it more perfect and reasonable.
This draft has determined the seismic fortification categories of 167 devices, including chemical mines, fertilizers, inorganic chemical raw materials, organic chemical raw materials, synthetic materials, fine chemicals, rubber processing, coking chemical production, and plant-wide auxiliary systems, which can basically meet the requirements of chemical engineering design. This standard is consistent with the petrochemical industry standard "Classification of Seismic Fortification Levels of Petrochemical Enterprise Buildings" (SH 3049-93) in the fertilizer, petrochemical and other parts are repeated, in the preparation of the two industries to make the standards consistent, so as to facilitate the use of designers.

Explanation of the provisions for the scale division of chemical and petrochemical enterprises
1.0.1 This standard is specially formulated to make the seismic design of chemical enterprise buildings and structures have clear fortification categories, to reduce earthquake disasters and to use construction funds reasonably. 1.0.2 This standard is formulated according to the principles of the national standard "Classification Standard for Seismic Fortification of Buildings" (GB50223-95) and the characteristics of the chemical industry. 1.0.3 This standard is applicable to the classification of seismic fortification of single buildings and structures for chemical production, transportation and storage in areas with seismic fortification intensity of 6 to 9 degrees. 1.0.4 The seismic fortification intensity or design earthquake motion parameters of the construction area shall be determined in accordance with the regulations of the relevant national departments.
1.0.5 When implementing this standard, it shall also comply with the requirements of the current relevant national standards and specifications. t
2 Technology. 2.0.1 Earthquake protection category In earthquake-resistant design of buildings, the classification of buildings and structures is based on the economic losses and social impact caused by earthquake damage or secondary disasters, as well as their role in earthquake relief. 2.0.2 Direct economic loss due to earthquake Direct economic loss due to earthquake Economic losses caused by the destruction of buildings, structures, equipment and facilities or the damage caused by secondary disasters, and the reduction in net output value due to suspension of production and business. 2.0.3 Indirect economic loss due to earthquake Indirect economic loss due to earthquake Social output value and other losses caused by suspension of production due to the destruction of buildings, structures, equipment and facilities or the damage caused by secondary disasters, the cost of repair and insurance compensation, etc.
2.0.4 Social effect due to earthquake mainly refers to the loss caused by the destruction of chemical buildings and structures and the deterioration of living conditions and welfare conditions, as well as ecological environment pollution. 2
3 Basic provisions
The classification of earthquake-resistant fortification of chemical buildings and structures should be comprehensively considered according to the following principles: 3.0.11
1 The social impact and direct and indirect economic losses caused by the destruction of buildings and structures caused by earthquakes and the leakage of harmful substances such as fire, explosion, toxic gas, and radiation;
2 The characteristics of the products, the size of the enterprise scale, and the scope of the global impact after the use function of the building and structure fails;
3 The seismic potential of the structure itself and the difficulty of restoring the use function: 4 When the importance of each unit of the building and structure is significantly different, the classification can be divided according to the local unit.
3.0.2 The seismic fortification categories of chemical industry buildings and structures are divided into four categories: Class A, Class B, Class C and Class D according to the principles of Article 3.0.1 of these Regulations. The classification shall meet the following requirements. 1 Class A buildings and structures are those that will have a serious impact on society, cause huge losses to the national economy or have special requirements after being damaged by an earthquake; 2 Class B buildings and structures are mainly those whose use functions cannot be interrupted or need to be restored as soon as possible, and whose damage by an earthquake will cause major social impact and major losses to the national economy. Including the main production buildings and structures of production facilities of super-large, large and medium-sized chemical enterprises, as well as buildings and structures that play a key role in normal operation; the main factory buildings, storage facilities and control system buildings and structures in production facilities with highly toxic, flammable and explosive substances; the heating, power supply, steam supply, water supply, refrigeration and other factory-wide buildings and structures of super-large, large and medium-sized chemical enterprises; the factory-wide communication, fire protection, earthquake disaster prevention and production command center buildings, warehouses for storing flammable, explosive, highly toxic and a small amount of radioactive dangerous goods, and flammable and explosive finished product storage tanks. Class B buildings and structures are further divided into Class B1 and Class B2 according to their importance. 3. Class C buildings and structures are generally affected after being destroyed by an earthquake, such as general production buildings and structures and buildings and structures that do not belong to Class A, B, and D. 4. Class D buildings and structures are buildings and structures whose destruction or collapse by an earthquake will not affect the use of the above-mentioned buildings and structures, and whose social impact and economic losses are minor; - Generally, these are single-story warehouses with low-value stored goods and few personnel activities. 3.0.3 The seismic fortification standards for various types of buildings and structures shall meet the following requirements: 1 For Class A buildings and structures, the seismic fortification intensity shall be designed one degree higher than the seismic fortification intensity of the region (including seismic action and seismic measures); 2 For Class B buildings and structures, seismic action shall be adopted according to the seismic fortification intensity of the region; seismic measures can be divided into the following two levels according to the scale and characteristics of the buildings and structures, based on the principles of seismic safety and economy:
