Uncertainty in Characteristic Strength of Historic Steel Using Non-Destructive Techniques
Original language description
The mechanical properties of historic metal materials exhibit a considerable scatter dependent on periods of construction and the region of a producer. Assessments of historic structures then need to be based on measurements and tests. The use of non- or minor-destructive tests (NDTs) is often preferred over to destructive tests (DTs) to reduce the cost of structural survey. Limited attention has been paid to the investigation of uncertainties in characteristic strength estimates based on NDTs so far. The contribution thus explores the measurement errors associated with common NDT hardness techniques (Brinell, Rockwell, Vickers, Poldi hammer, Leeb) and quantifies uncertainties in characteristic strength estimates. The measurement uncertainty is assessed considering the database of 119 pairs of NDTs and DTs taken from buildings and bridges from the 19th century.
