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。
