London Landmarks and The Millennium Bridge - Essay Example

The problem, as already mentioned, was swinging on deck when the huge crowd of nearly 80,000 steps on an opening day. This created a panic among not only individuals but also the engineers because of excessive volatility. Accordingly, the bridge was closed temporarily from June 12, 2000. (The Millennium Bridge, 2011)After investigation, it was discovered that the main reason for the swing bridge is not weakness, but people walking style. This phenomenon was known as the synchronous lateral excitations.

This meant that the natural way of walking caused by human lateral oscillations cause the bridge to swing sideways. (London Landmarks, 2011)Research and experiments led to the suggestion of introducing damping mechanisms to absorb the pressure or the vibration of people walking. Depreciation is not only beneficial to absorb pressure and oscillation, but it is not visible. This is due to damping mechanisms are mainly at the bottom of the structure. Therefore, the issue has been addressed effectively and was a signal for future structures.
