1915 Canakkale Bridge AMDs Being Lab Tested
The 1915 Çanakkale Bridge is the world’s longest suspension bridge, with a total length of 3,623 meters. It features towers over 300 meters in height, a main span of 2,023 meters, and side spans of 800 meters each.
The primary objective of the vibration control system for the Çanakkale Bridge was to suppress vortex-induced vibrations (VIV) to acceptable levels during both the construction phase and service life of the bridge. This was essential to prevent fatigue-related degradation of the bridge's lifespan. Additionally, the system aimed to reduce wind-induced vibrations of the towers to improve workability for construction personnel during erection and enhance serviceability for users during operation.
To achieve this, six Active Mass Dampers (AMDs), each with a moving mass of 30 tons and a stroke of ±1.2 meters, were deployed during the construction phase to effectively suppress wind-induced vibrations. During the operational phase, four AMDs continue to control the tower vibrations. Performance tests confirmed that the damping targets were successfully achieved, and that no VIV occurred while the AMDs were in operation.
