scope:

This International Standard provides guidelines for dynamic tests and investigations on bridges and viaducts. It - classifies the testing as a function of construction and usage, - indicates the types of investigation and control for individual structural parts and whole structures, - lists the equipment required for excitation and measurement, and - classifies the techniques of investigation with reference to suitable methods for signal processing, data presentation and reporting. This International Standard provides general criteria for dynamic tests. These can supply information on the dynamic behaviour of a structure that can serve as a basis for condition monitoring or system identification.
