Uncertainty in NDT Assessments of Historic Steel Bridges
Original language description
Sustainable development can be supported by extending the service lives of existing bridges. Preservation and upgrades should be based on improved structural assessments, monitoring, and strengthening methods. In the case of metallic materials, hardness methods (NDT) calibrated by a few tensile tests (DT) were shown to be associated with reasonable measurement uncertainty. This contribution discusses the current practice in NDT assessments and introduces the hierarchical modeling of the measurement uncertainty in hardness tests. Based on a limited database, preliminary results concerning measurement uncertainty in hardness methods suggest that variability of a material property can hardly be estimated on the basis of NDTs only. The systematic component of measurement uncertainty has a lower coefficient of variation (3%) than the random component (8%); the variability of the latter may thus often exceed the variability of ultimate strength of a homogeneous material.
