Abstract
Monitoring of the objects is executed primarily to determine outer and inner influences on the object and mostly for the sake of the safety of people, animals, and material assets. The monitoring can be executed with various methods which depend on the object, conditions for the execution and the purpose of the monitoring. Our focus lies in the monitoring of the footbridge over the Lobnica creek in the town of Ruše in Slovenia. The monitoring of the vibrations and displacements was carried out as the loading test under the influence of the dynamic load with the purpose to determine the elastic response. The elastic response of the very decrepit footbridge was one of the conditions for decision about the meaningfulness of the renovation of an extremely corrosive damaged bridging object. For this purpose, the physical methods were used with the application of the seismograph, the micrometre and geodetic method with the robotic total station (RTS), which was controlled in two ways: by the built-in Leica GeoCom protocol and additional software GeoCom/Zg. The emphasis of the experiment was on the application of the non-contact geodetic methods, which are nowadays in use for the measurements of the dynamic response and enable the measurements with the RTS up to 30 Hz.
The article presents the application of various procedures of non-contact data including the bridge, comparison, and the analysis of the obtained values in the dynamic response monitoring of the construction.
