I always thought Millennium Bridge is at Brighton after some guys from IStructE told me to see what's wrong with the bridge. At first I thought this might be another Millennium Bridge since I saw one in Scotland. Jeff told me it was a nationwide idea to build one Millennium Bridge in each states to usher in the Y2K. Located opposite the St. Paul Cathedral, this pedestrian bridge is quiet long. This steel structure was once closed from operation due to Synchronous Lateral Excitation.Left Pyshic s for quite a while heh? Still remember resonance? When one frequency is same with the natural frequency of that item, it will cause excitement (vibration). But the engineer eventually fixed it by putting some dampeners to "absorb" the vibration. Nevertheless, I didn't cross the bridge. Why? Because I'm an engineer myself too.
