建筑抗震设防分类标准
（GB50223—95）
1．总 则
1.0.1 为使建筑的抗震设计有明确的设防等级，以合理使用建设资金，减轻地震灾害，特制定本标准。
1.0.2 本标准适用于设防烈度为6～9度地区的建筑抗震设防分类。
1.0.3 有特殊要求的建筑和本标准未列的行业的建筑抗震设防等级，由有关部门根据实际情况比照本标准做专门规定。
1.0.4 各行业、各部门的建筑抗震设防等级的行业标准，应符合本标准对建筑的抗震设防等级标准的原则要求和规定。
2．术 语
2.0.1 抗震设防等级划分 抗震设计中，根据建筑遭遇地震破坏后经济损失和社会影响程度及其在抗震救灾中的作用，对建筑所作的设防等级分类。
2.0.2 直接经济损失 建筑及设备、设施本身破坏的损失，以及其停产所受的损失。
2.0.3 间接经济损失 建筑及设备、设施破坏，导致停产所减少的社会产值，修复所需费用，救灾费用以及保险补偿费用等。
2.0.4 社会影响 主要指建筑破坏导致人身伤亡和居住条件、福利条件、生产条件以及生态环境污染等造成的损失。
2.0.5 动力系统建筑 指供电、供热、供水、供气系统的建筑。
3．基本规定
3.0.1 建筑抗震设防等级的划分，应综合考虑下列原则：
3.0.1.1 社会影响和直接、间接经济损失的大小。
3.0.1.2 城市的大小和地位、行业的特点、工矿企业的规模。
3.0.1.3 使用功能失效后对全局的影响范围大小。
3.0.1.4 结构本身的抗震潜力大小、使用功能恢复的难易程度。
3.0.1.5 建筑各单元的重要性有显著不同时，可考虑进行局部的等级划分。
3.0.1.6 在不同行业之间的相同建筑，由于所处地位及受地震破坏时产生后果及影响的不同，其抗震设防等级可以不同。
3.0.2 建筑应按其使用功能的重要性，分为甲、乙、丙、丁四类，其划分应符合下列要求：

Seismic fortification classification
(GB50223-95)
1. General
1.0.1 In order to seismic design of buildings have a clear fortification levels, to the rational use of construction funds, reduction of earthquake disasters, the standard is formulated.
1.0.2 This standard applies to fortification of 6 to 9 degrees region of the building earthquake-proof category.
1.0.3 there are special requirements and the standards listed building construction industry seismic fortification level, the actual situation by the authorities under the criteria for special provisions cf.
1.0.4 all industries, all sectors of building seismic fortification level of industry standards, should meet the standards of the building principles of seismic fortification level of standard requirements and regulations.
2. Terminology
2.0.1 Classification of seismic design of earthquake-proof, according to construction after earthquake damage suffered economic losses and social impact and its role in earthquake relief, the maximum security level of the building classification.
2.0.2 Direct economic losses construction and equipment, facilities, the loss of their own destruction, as well as the loss of its shutdown.
2.0.3 indirect economic losses construction and equipment, facilities damaged in the reduction of social production shutdown, repair costs, disaster relief costs and insurance compensation costs.
2.0.4 The societal impacts that result in personal injury and destruction of buildings housing conditions, benefits, production conditions and ecological losses caused by environmental pollution.
2.0.5 Power system architecture that power supply, heat supply, water supply, gas supply system of the building.
3. Basic requirements
3.0.1 The classification of earthquake-proof buildings, should be taken into account the following principles:
3.0.1.1 Social influence and direct and indirect economic losses size.
3.0.1.2 The size and status of the city, industry characteristics, the scale of industrial and mining enterprises.
3.0.1.3 after using disable the size of the global sphere of influence.
3.0.1.4 Structure of the seismic potential of their size, ease of use of functional recovery.
3.0.1.5 The importance of building the unit was significantly different time, could be considered a partial classification.
3.0.1.6 In the same building between different industries, because of their positions and destroyed by the earthquake consequences and impact of different levels of their seismic fortification may be different.
3.0.2 Building the importance of its function should be divided into A, B, C, D four categories, the division shall meet the following requirements:
