The monitoring of dynamic parameters of slender bridge structures is becoming of particular interest in terms of their possible use in determining their structural condition, or possibly as one of the parameters for their long-term monitoring. The method for monitoring dynamic parameters is relatively new and practically unexplored. First of all, it is necessary to find out with certainty how the dynamic parameters of slender bridge structures change, for example, with changes in temperature, the magnitude of the prestressing force, or how they change with changes in discontinuous mass (e.g. overlaying or stripping of pavement layers). The paper summarizes the important aspects that can affect the modal parameters - natural frequencies and their shapes. The above listed influences and their impact on the structure were investigated on real structures formed by stress ribbon.

Klíčová slova
