同步侧向激励或人激励横向桥梁振动主要发生在横向模态阻尼较轻且具有较低的摇摆运动固有频率的结构上。这两个条件都直接适用于有关的主题，伦敦的千禧桥，同样可以避免通过加强结构，以提高其固有频率。摇摆运动的固有频率必须在激励的频率范围之外。结构更多的是艺术设计，同样可能已经通过加强妥协。然而，在施工过程中同样是一个不希望的方面。因此，在构建一个艺术桥梁，它是必不可少的，必不可少的方面得到充分照顾和适当的测试上进行较小的模型的结构。
故障也可以避免通过增加固有的低阻尼的桥梁。很明显，运动主要建立在阈值阻尼水平以下，因此，通过增加阻尼水平，施工人员可以确保自我激励不会发生。的初始结构也可以被纳入超过50调谐质量减振器和37线性粘滞阻尼器。同时进行桥梁从未动摇或摇摆不定的那一天。这可以被看作是从失败中学习的实际例子。
这座桥从未与桥梁的物理结构相吻合，更像是一种艺术设计。然而，桥梁的晃动更多的是由于人们在整个失败过程中行走的行为。摇摆或晃动的伦敦千禧桥也可以被解释为推秋千上的人。它并不需要很大的努力，使人摆动，但是，同步必须有。类似的事情发生在千禧桥上的人走在桥上同步他们的腿与缓慢摆动的桥梁运动。

The synchronous lateral excitation or people – excited lateral bridge vibration mainly occurs on the structures for which the damping is light on lateral modes and has lower natural frequencies of the movement of swaying. Both the conditions are directly applicable on the concerned subject, London’s Millennium Bridge; the same could have been avoided through stiffening the structure to enhance its natural frequencies. The natural frequencies of the swaying movement must be taken outside the frequency range of excitation. The structure was more of an artistic design and the same could have been compromised through stiffening. However, during the construction the same was an undesirable aspect. Thus, before constructing an artistic bridge, it is essential that essential aspects are adequately taken care of and proper tests are performed on the smaller model of a structure.
The failure could also been avoided through increasing the inherently low damping of the bridge. It is also clear that the motion builds up mainly below the threshold damping level, thus through increasing the damping level, the constructors could have ensured that self – excitation does not occur. The initial structure could also been incorporated with more than 50 tuned mass vibration absorbers and 37 linear viscous dampers. The same was performed and the bridge has never swayed or wobbled from that day. This can be perceived as the practical example of learning from failure.
The bridge was never constructed in alignment with the physics of bridges and was more of an artistic design. However, the swaying of the bridge was more because of the behavior of people that were walking on it during the whole failure happened. The swaying or wobbling of the London’s millennium bridge can also be explained as the push to a person on swing. It does not take much effort to make the person swing; however, the synchronization must be there. The similar thing happened on the millennium bridge as the people walking on the bridge synchronized the movement of their legs with the slow swaying of bridge.
