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.

Abstract: A plurality of strain values are received from a plurality of sensors permanently attached to an asset configured to carry a load. A strain profile of the asset is monitored based on the plurality of strain values. Additional information about the asset is received. A load rating factor is monitored based on the additional information and the strain profile. An equivalent accumulated damage factor is monitored based on the load rating factor. A remaining life prediction for the asset is calculated based on the strain profile and the equivalent accumulated damage factor.
