英国建筑学论文代写：桥梁故障的原因
有关桥梁的故障也表明，每座桥梁的设计都是根据在特定地点吹来的风的速度而设计和制定的。然而,走在桥上的人们更负责任,而不是桥的设计,低水平摇摆的桥梁由于强风的关键原因是人失去了平衡,从而试图平衡自己,并最终开始同步他们的脚的动作摇晃的桥。
大桥的结构从来没有被用来吸收风力，这是桥梁失效的主要原因之一。当人们开始用摇摆的桥来同步他们的脚动时，形成了一个反馈环。正是这种反馈回路具有自然的共振频率，因此人们的步行速度与桥的运动相匹配。毫无疑问，在不久的将来避免这种情况的唯一方法是尽可能使桥梁和其他结构保持稳定。
除了阻尼,电缆和材料用于构造的悬索桥也必须质量水平,所以,即使设计未能适应风吹,材料可以很容易地吸收振动的强度,或者车辆在桥上的人永远不会有同样的感觉。然而，在悬索桥上完全消除振动几乎是不可能的，稳定剂的利用仍然是避免此类事故的最有效方法。伦敦千禧桥的失败并不新鲜，因为类似的案例也在早些时候被发现。因此，任何吊桥的设计首先要通过其较小的模型进行测试，而风险要素被完全根除。

The failure of the concerned bridge also depicts that the design of each bridge was be developed and formulated on the basis of the speed of wind that blows at that particular location. However, the people walking on the bridge were much more responsible rather than the design of bridge, the low level swaying of bridge due to heavy winds was the key reason that the people lost their balance and thus attempted to balance themselves, and eventually started synchronizing their foot movements with the swaying of bridge.
The structure of the bridge was never made to absorb the wind that acted as one of the key reasons of the failure of bridge. There was a feedback loop that was formed as the people started synchronizing their foot movements with the swaying of bridge. It was this feedback loop that had a natural resonant frequency and thus the walking pace of people matched the movement of bridge. Undoubtedly, the only way to avoid such situations in near future is to make the bridges and other structures as stable as possible.
Other than damping, the cables and the material used to construct the suspension bridges must also be of the quality level, so that even of the design fails to adapt the blowing wind, the strength of the material can easily absorb the vibrations and the people or the vehicles on the bridge never feel the same. However, eradicating the vibrations completely on suspension bridge is nearly impossible and utilization of stabilizers remains the most effective method to avoid such incidents. The failure of the London’s Millennium Bridge was not new as the similar cases were seen earlier as well. Thus, it is essential that the design of any suspension bridge is first tested through its smaller model and the risk elements are completely eradicated.
