Structures made of structural concrete are designed to withstand different time‐dependent or time‐independent influences during their expected service lifetime. Most of these influences can be considered in a sufficient manner by mathematical and statistical approaches, while some do appear combined with certain structural, environmental, and material boundary conditions. These can, in most cases, not be foreseen, verified or they change during the lifecycle of a concrete structure. It is therefore obligatory to rely on an efficient conservation strategy for each structure to ensure its safety and overall economic efficiency. For this purpose, the fib Model Code for Concrete Structures 2010 already suggests a general workflow to follow a predefined or provisional conservation strategy and condition control procedure. These existing proposals are yet of very general nature and disclaim practical decision‐making rules to survey and assess existing structures as part of a condition‐based conservation strategy. In this contribution, the main decision‐making options at an early stage of a construction's life cycle management are pointed out, considering their importance for a structure's time‐dependent performance and their relation to continuative decisions for conservation management. Proposals for the implementation of practical advice for condition‐based conservation strategies in international guidelines are made.

结构的有效生命周期管理的决策

结构混凝土制成的结构旨在在预期使用寿命内承受不同的时间依赖性或时间依赖性影响。可以通过数学和统计方法以充分的方式考虑所有这些影响，而某些影响确实与某些结构，环境和材料边界条件结合在一起。在大多数情况下，无法预见，验证或在混凝土结构的生命周期内更改这些内容。因此，必须对每个结构都采用有效的保护策略，以确保其安全性和总体经济效率。为此，fib混凝土结构标准规范2010已建议遵循预定或临时的养护策略和条件控制程序的一般工作流程。这些现有建议仍具有非常普遍的性质，并且不接受作为基于条件的保护策略的一部分来调查和评估现有结构的实用决策规则。在此贡献中，指出了建筑生命周期管理早期的主要决策方案，考虑了它们对于结构随时间变化的性能的重要性以及与保护管理的连续决策的关系。提出了在国际准则中实施基于条件的保护策略的实践建议的建议。
