Announcement No. 70 of the Ministry of Housing and Urban-Rural Development of the People's Republic of China

The Classification Standard for Seismic Fortification of Construction Engineering is now approved as the national standard, numbered GB50223-2008, and will be implemented as of the date of publication. Among them, Articles 1.0.3, 3.0.2, and 3.0.3 are mandatory provisions and must be strictly implemented. The original "Classification Standard for Seismic Fortification of Construction Engineering" GB50223-2004 was abolished at the same time.

This standard is published by China Construction Industry Press organized by the Standard Quota Research Institute of our Ministry.

Foreword

This standard is based on the requirements of the Ministry of Construction [2008] Jianbi No. 65, and was revised by the China Academy of Building Sciences in conjunction with relevant design, research and teaching units to the "Classification Standard for Seismic Fortification of Building Engineering" GB 50223-2004 .


During the revision process, a preliminary survey summarized the lessons learned from the Wenchuan earthquake: after the 1976 Tangshan earthquake in China, the Ministry of Construction made earthquake-resistant fortifications starting at 6 degrees and fortified with a "big earthquake" that was once stronger than the fortification intensity. The decision of the target for seismic design is correct. The Wenchuan earthquake shows that buildings designed, constructed and used in strict accordance with current regulations have not collapsed due to an earthquake that was one degree higher than the local fortification intensity, effectively protecting people's lives.


This revision takes into account that China's economy has developed significantly. According to the "intensive public service facilities such as schools, hospitals, stadiums, museums, cultural centers, libraries, theaters, shopping malls, transportation hubs, etc., The requirements for seismic fortification of buildings are designed to enhance the capability of seismic fortification ", which has increased the seismic fortification categories of certain buildings, and has solicited opinions from relevant design, scientific research, teaching units, and seismic management departments across the country. , After repeated discussions, amendments, and enrichment, the final review and finalization.


This revision continues to maintain the classification principles of the 1995 and 2004 editions: in view of the fact that all buildings are required to achieve the "fortified earthquake" fortification target, the buildings that require higher seismic fortification requirements than ordinary buildings are controlled to a smaller extent, and Measures are taken mainly to improve the resistance to collapse and deformation.


There are 8 chapters in this standard after revision. The main amendments are as follows:


1. Adjusted the definition and connotation of classification.

2. Especially strengthen the protection of minors in emergencies such as earthquakes.

3. The scope of personnel-intensive buildings was expanded, and the earthquake-resistant capacity of personnel-intensive public service facilities such as hospitals, stadiums, museums, cultural centers, libraries, theaters, shopping malls, and transportation hubs was improved.

4. Added requirements for buildings in earthquake shelters and electronic information centers.

5. It is further clarified that the names of the buildings listed in this standard are examples. Buildings not listed in this standard may determine their seismic fortification categories according to examples of similar functions and scale.


This standard may need to be partially revised in the future. Information and provisions about the partial revision will be published in the "Engineering Construction Standardization" magazine.


The specific interpretation of this standard is the responsibility of the Engineering Earthquake Research Institute of the Chinese Academy of Building Sciences. In the process of implementation, all units are required to combine engineering practice, carefully summarize their experience, and send their opinions and suggestions to the management group of the National Standard for Seismic Fortification Classification of Building Engineering, China National Academy of Building Sciences, No. 30 Beisanhuan East Road, Beijing ( Zip code: 100013, E-mail: ieecabr @ cabr.com.cn)
