1 总则

1.0.1 为贯彻执行国家和河北省的有关法规和技术政策，在消能减震工程中做到安全适用、技术先进、确保质量，制定本标准。

1.0.2 本标准适用于河北省抗震设防烈度为 6 度～8 度地区新建建筑的消能减震设计、施工、质量验收和维护。

1.0.3 按本标准设计与施工的消能减震结构，其抗震设防目标分为两类：

第一类：当遭受低于本地区抗震设防烈度的多遇地震影响时，消能部件正常工作，主体结构不受损坏或不需要修理可继续使用；

当遭受相当于本地区抗震设防烈度的设防地震影响时，消能部件正常工作，主体结构可能发生损坏，但经一般修理仍可继续使用；

当遭受高于本地区抗震设防烈度的罕遇地震影响时，消能部件不应丧失功能，主体结构不致倒塌或发生危及生命的严重破坏。

第二类：当遭受低于本地区抗震设防烈度的多遇地震影响时，消能部件正常工作，主体结构不受损坏；当遭受相当于本地区设防烈度的地震影响时，消能部件正常工作，主体结构基本不受损坏或不需修理可继续使用；当遭受高于本地区抗震设防的罕遇地震时，消能部件正常工作，主体结构可能发生损坏，经修理仍可继续使用。

1.0.4 消能减震建筑的结构构件、非结构构件和附属设备的使用功能有专门要求时，除应符合本标准抗震设防目标外，尚应符合结构构件、非结构构件和附属设备抗震性能标准的规定。

1.0.5 采用消能减震技术的建筑工程的设计、施工、质量验收和维护，除应符合本标准外，尚应符合国家和河北省现行有关标准的规定。
