Özet
Suspension bridges are affected by the loads like temperature changes, traffic, pedestrian and wind. When designing the structure, all possible loads are considered. But sometimes unexpected activities may occur on these kinds of structures. For example, the Eurasia Marathon is one good example of unexpected activity for the Bosporus Bridge, which was affected by different activities and loads such as rhythmic, systematic, and random pedestrian running during this event. These loads have been used to obtain the dynamic characteristics of the Bosporus Bridge in Istanbul, Turkey. The field ambient vibration measurements on the bridge deck were conducted during the 27(th) Intercontinental Eurasia Marathon on 02. October. 2005. Vibrations of the bridge were determined by using Wavelet Transform in the time-domain. It was seen that the rhythmic run was caused rhythmic vibrations in the vertical direction. Any negative response did not determine. Because this rhythmic effect was continued in short time. Otherwise, if the vibration of rhythmic running and the natural vibration of the bridge coincided, considerable vibration problems could have occurred on the bridge. In this kind of situation, the effect of coercive forces may increase and some risks may occur for the bridge. Also when traffic load was effective, explicit movements were determined.
