How much can that rope-mounted bridge swing to make it even safer for cars? This problem worries many engineers, so in China, police rushed to block the bridge and ban its use as soon as it was possible to grab all drivers.
The video posted with a swing bridge reminded me of a Tacoma Narrows suspension bridge in Washington, USA. USA This bridge also arose, and eventually such a “surge” ended in the collapse of the bridge.
The Tacoma Narrows Bridge is said to have collapsed four months after it opened, withstanding 64 km / h. wind
Although the Tacoma Narrows Bridge is often said to have collapsed due to resonance, in fact, it turned out that the bridge was poorly designed and not very strong as it saved steel during construction.
All structures must be strong and resist some of those movements. Chinese authorities soon explained that such oscillation of the bridge was due to the construction of a new wall near the bridge, which was opened 20 years ago.
Such a change caused the surface of the bridge to move up and down. And if this was not noticed on a normal day, the storm surge of the bridge intensified as necessary in case of a particularly strong wind.
The wall is planned to be demolished and drivers are not expected to see similar images. Still, it will probably take time for drivers to feel bold again on this road.
