Announcement on Publishing the National Standard “Standard for Classification of
Seismic Protection of Building Constructions”
Standard for Classification of Seismic Protection of Building Constructions has been
approved as a national standard with a serial number of GB 50223-2008, and shall be
implemented from the date of promulgation. In the Standard, articles 1.0.3, 3.0.2 and 3.0.3 are
compulsory articles, and must be implemented strictly. The former "Standard for
Classification of Seismic Protection of Building Constructions" GB 50223-2004 shall be

1Foreword
According to the requirements of the Document Jianbiao [2008] No. 65 issued by the
Ministry of Construction, this standard is revised from the former standard "Standard for
Classification of Seismic Protection of Building Constructions" GB 50223-2004, by China
Academy of Building Research (CABR) together with related design, research and teaching
organizations.
In the revision process of the standard, the experience and lessons about Fenchuan
earthquake was summed up through preliminary investigation. after Tangshan earthquake
(1976), the Ministry of Construction made the provision that the earthquake-resistant design
of building construction shall be taken out based on degree 6 and the non-collapse protection
target that the actual earthquake protection is one-degree higher than the normal fortification
intensity. Fenchuan earthquake indicated that buildings, that are designed, constructed and
used strictly in accordance with the current provision, occur no collapse and failure when the
buildings suffer from the earthquake effect that is one-degree higher the local fortification
intensity. The lives of the people have been protected effectively.
With a view to the rapid development of our country, based on that "for person-intensive
public facilities such as school, hospital, gymnasium, museum, culture center, cinema, theater,
shopping plaza, and transport junction, the design shall be taken out in accordance with the
requirement of earthquake protection higher than local building construction's, to improve the
earthquake protection capacity", increase the earthquake protection type of some buildings;
widely ask for opinions of relative design, research and teaching organizations, as well as
earthquake resistance administrative authority; carry out discussion, revision and supplement
many a time; and finalize the standard by the examination.
The revision holds over the classification principle of edition 1995 and edition 2004.
whereas, all buildings shall meet the requirements of earthquake protection target "No
collapse in large earthquake", buildings that shall be designed based on the earthquake
protection degree one-degree higher than the normal buildings are limited within smaller
range, and measures to improve the collapse and deformation resistance shall be required.
The revised standard is consisted of 8 chapters totally. The main contents of the revision
are as follows.
1. Adjust definition and intension of the categories.
2. Specially strengthen the protection for the infants under accidents like earthquake.
3. Expand the range of person-extensive building; increase the earthquake resistance that
person-extensive public facilities such as hospital, gymnasium, museum cultural center,
library, cinema, theater, shopping plaza, and transport junction shall comply with.
4. Add the requirements on earthquake refuge building and electronic data centre.
5. Further definite that construction names listed in the standard are instance names, and
for construction not listed on the standard, the earthquake protection type may be identified
according to the instance construction similar in function and scale.
Local part of the standard may be revised according to concrete requirements in the future,
and relevant revision information and content will be published on "Standardization of
Engineering Constructions".

Summary This Chinese standard relates to fortification construction of seismic design categories and corresponding seismic standards, in order to effectively reduce the earthquake disaster, the development of this standard. This standard applies to seismic zone classification of seismic construction projects. Seismic zone all construction works shall determine its seismic category. New construction, renovation, expansion of the building works. Category should not fall below its seismic requirements of this standard. Developed classification of seismic construction industry standards, this standard shall comply with the principle of segregation. This standard does not have special requirements listed in the construction, classification of seismic its special provisions should be implemented.
