The millennium bridge is a simple suspension bridge and was likely to swing because of the wind, but the synchronization of the people’s walk gave the bridge an extra push and in spite of swinging, it wobbled. Thus, the wobbling of the millennium bridge is not just an example to the architects but also to the general public as the people must understand the dynamics of a suspension bridge.
The concerned bridge is flexible and it swayed a little because of both the foot traffic and the wind at first. The slight movement of the bridge led the people following the same swaying and thus the average walking place of people on the bridge matched the frequency of swaying. The wobbling of the bridge clearly demonstrated the importance of stabilizer and damping on the bridges as beautification can be compromised but the safety cannot. It is also evident that the wobbling of the bridge was the consequence of a lateral loading effect that was not anticipated by the constructors during the finalization of bridge design.
The whole issue helps in gaining a better understanding of the most effective suspension bridge structure. It was known and expected that the bridge will get crowd and thus the failure of the bridge could have been avoided through stabilizing the bridge much more. The key lesson learned from the failure of London’s Millennium Bridge is that the bridge is a way of transportation and must not be compromised for just beautification. Other than this, it is essential that the constructors and other higher authority make sure that any kind of structure is stable enough and is capable of absorbing the heavy mass and the wind. However, the people are blamed more than the constructors. More number of tuned mass vibration absorbers and linear viscous dampers was the responsibility of the constructors.
