混凝土结构的耐久性设计已为世界土木工程界所关注,本文简要介绍了《混凝土结构耐久性设计规范》的主要内容及该规范对混凝土耐久性的设计原则,规范在环境类别的基础上加入了环境作用等级的划分,对结构构件处于不同环境等级的作用下采取相应不同的设计要求。该规范将对我国处在高速发展阶段的混凝土工业借鉴国际经验,提高使用年限,避免不必要的经济损失起到重要作用。
The durability design of concrete structures has been the focus of the world civil engineering community. This paper briefly introduces the main content of the “Design Code of Durability of Concrete Structures” and the design principles of the specifications on the durability of concrete. The rules are based on the environmental categories The division of environmental effect levels, the structural components in different environmental levels under the effect of taking the appropriate design requirements. The norm will play an important role in reference to international experience in concrete industries that are in a stage of rapid development in our country, improving the service life and avoiding unnecessary economic losses.
