Abstract
A set of load responses of an asset for a sample of traffic loading events caused by objects of unknown weight is measured. At least one statistical parameter is determined from the set of load responses. A corresponding statistical parameter of known object weights loading the asset is determined. An object weight is assigned to a load response of the set of load responses based on correlation of the extracted statistical parameter to the corresponding statistical parameter.
Claims20
A method comprising:
- measuring a set of load responses of an asset for a sample of traffic loading events caused by objects of unknown weight passing over the asset;
- determining at least one statistical parameter from the set of load responses;
- determining a corresponding statistical parameter of known object weights of a population of objects assumed to be loading the asset;
- assigning an object weight to a load response of the set of load responses based on correlation of the at least one statistical parameter to the corresponding statistical parameter;
- and
- inferring a structural health of the asset from observing the load response and the object weight.

A system, comprising:
- sensors disposed on an asset and configured to measure a set of load responses of the asset for a sample of traffic loading events caused by objects of unknown weight passing over the asset;
- a database of known object weights of a population of objects assumed to be loading the asset;
- and
- a processor configured to:
- determine at least one statistical parameter from the set of load responses;
- determine a corresponding statistical parameter of the known object weights loading the asset;
- assign an object weight to a load response of the set of load responses based on correlation of the at least one statistical parameter to the corresponding statistical parameter;
- and
- infer a structural health of the asset from observing the load response and the object weight.
