本文件提供了在规划、设计、执行、使用和寿命结束阶段实施混凝土结构生命周期管理（LCM）的原则，以及LCM的框架和程序。 本文件不仅适用于新结构，也适用于现有结构。它也适用于整个生命周期以及构成结构生命周期的每一个或多个阶段。 注:基于本文件的结构生命周期每个阶段的管理程序和具体方法的细节是单独制定的。

This document provides the principles for implementing life cycle management (LCM) of concrete structures throughout the stages of planning, design, execution, use and end-of-life, as well as the framework and procedures for LCM. This document is applicable not only to new structures but also existing structures. It is also applicable to the entire life cycle and each one or more stages composing the life cycle of a structure. NOTE Details in the procedures and specific methodologies for management in each stage of structure's life cycle based on this document is established separately.
