Tension bar systems under cyclic loading - Measuring of eigenfrequencies of tension bars on Troja bridge
Original language description
The aim of the research presented in this paper is to clarify the behaviour of tension bar systems under cyclic loading. These components are exposed to climatic conditions, especially to dynamic wind load, which may cause vibrations. Members used on bridges are additionally subjected to effects of cyclic traffic loads. Both dynamic wind load and traffic loading are major factors causing high-cycle fatigue of civil engineering structures. At this time, no global research in area of tension bar systems is being conducted. The experimental in-situ measuring on the stays of Troja bow-string arch bridge is underway. The aim of the experiment is to get a representative sample of measurement for determination behaviour and boundary restraining conditions ofstays made from tension bar systems. Uncertainty exists in the accuracy of the value of logarithmic decrement of the damping. Currently it is possible to obtain values for cables but not as easy for tension bar systems.
