Mechanical vibration - Evaluation of measurement results from dynamic tests and investigations on bridges
ISO 18649:2004 provides methodology for the evaluation of results from dynamic tests and investigations on bridges and viaducts. It complements the procedure for conducting the tests as given in ISO 14963 and considers:
The dynamic tests considered in ISO 18649:2004 do not replace static tests.
ISO 18649:2004 gives guidance on the assessment of measurements carried out over the life cycle of the bridge. The stages of the life cycle that are considered are:
ISO 18649:2004 is applicable to road, rail and pedestrian bridges and viaducts (both during construction and operation) and also to other works, provided that they justify its application. The application of this International Standard to special structures (cable-stayed or suspension bridges) requires specific tests that take into account the particular characteristics of the work.
