Determination of static and dynamic response of structures with geodetic methods in loading tests

Abstract

The article presents the results from a static part of the load test for the Zglavje viaduct, located on the motorway A1 in Slovenia and the feasible usage of modern geodetic instruments for determination of dynamic response of a structure. Therefore, static analysis was employed for comparison of the implemented methods by which vertical displacements were measured and compared to a calculated displacement. High agreement of the results was established. In addition, experimental part of the geodetic non-contact methods to determine dynamic response of the structure was implemented on the railway bridge across the Mura river on the railway line Ormož–Hodos in Slovenia. Geodetic non-contact methods are evidently more and more applicable at determination of dynamic response for their technologic development in the area of speed and constant data capturing. Our results were provided by employing the Robotic Total Station (RTS).
