混凝土结构的生命周期管理 第2部分：结构规划和设计阶段

[中文适用范围]： 本文件适用于结构规划和设计阶段进行的管理，作为注的一部分。结构的基本设计或概念设计在结构规划阶段进行，而验证在设计阶段进行，以确认满足性能要求，并在设计时确保指定的可持续性指标的平衡。 [外文原描述]： The proposed document provides the life cycle management of concrete structures particularly focusing on the structural planning and design stage on the basis of the framework and general principles specified by ISO 22040, Life cycle management. This document is applicable to not only newly constructed structures but also existing structures when their life cycle is restarted. This document specifies on how performance requirements should be considered at the planning and design stage and also how the basic LCM scenario should be drawn up. Management items at the design stage are clearly defined and information that may be fed back to the planning stage and be transferred to the execution stage is described.
