摘要

评估现有结构中混凝土的抗压强度提出了一种基于(i)测量数据和（ii）设计阶段可用信息的概率方法来确定混凝土抗压强度的特征值和概率分布。所得混凝土抗压强度特征值，可用于验证。以半概率为部分安全概念，而概率分布可用于可靠性分析和进一步研究。该方法是在一个免费的web工具中实现的。

Ermittlung der Betondruckfestigkeit in Bestandsbauten

Assessing the compressive strength of concrete in existing structures

A probabilistic approach is presented to determine the characteristic values and the probability distribution of the concrete compressive strength based on (i) measurement data and (ii) information available from the design phase. The resulting characteristic value of the concrete compressive strength, , can be used for verifications acc. to the semi-probabilistic partial safety concept, while the probability distribution can be used for reliability analysis and further investigations. The approach is implemented in a freely available web tool.
