Remaining life prediction of existing reinforced concrete structures

为了通过统计表征来评估既有钢筋混凝土结构的抗压强度，本研究通过芯样对结构构件和非结构构件的抗压强度进行了比较。这些建筑竣工时的施工工艺对混凝土质量有很大影响。在此基础上，给出了用于结构剩余寿命预测的混凝土性能分布。

In this study, to evaluate the compressive strength of existing reinforced concrete structures by the statistical characterization, compressive strength of structural members were compared with non-structural members by core sampling. The construction technology at the time of the completion of these buildings has a large effect on qualities of concrete. As a result, the distribution of concrete properties for the prediction of remaining lifetime of structures was presented.
