Bridge collapse slogan

After cutting the ribbon, a good bridge will break immediately. Personally, I think there are two reasons. The first bridge has serious quality problems, which may come from the design or construction process; The second bridge exceeded the design weight and was overweight, which led to the collapse of the bridge.

It happened on a small bridge in Congo, which was a temporary bridge. For the convenience of local residents, it is used in flood season. It was a good thing to build such a bridge, but it became a global joke at the ribbon-cutting ceremony before the bridge was put into use.

After the ribbon-cutting ceremony, this very small bridge began to collapse before people celebrated. Not only did the bridge break in two, but even the deck collapsed. After watching the video, I also saw many netizens teasing, saying that ribbon-cutting plays an important role in carrying bridges. After cutting, the bridge cannot bear the load and will collapse.

The above statement is just a joke of netizens. In practical engineering, ribbon-cutting has no effect on bridge structure. There are two possible reasons why the bridge collapsed. No matter what causes exist, the bridge will collapse; Fortunately, the bridge collapsed when it was completed, not in the flood, and no casualties were caused.

There are defects in the design and construction of the bridge, which may make the stress structure of the bridge unreasonable, and then collapse after the bridge is loaded. This situation is often encountered in engineering. Both design and construction are very important. If any link goes wrong, the quality and service life of the bridge will be greatly affected.

In addition to this reason, when the bridge bears more weight than the design weight, it will collapse. This is also an important reason why almost all bridges in life have weight restrictions.

Limiting the maximum weight of the bridge is to ensure the safety and normal operation of the bridge structure. On the ribbon-cutting day, the bridge was crowded with people, which may have exceeded the design bearing capacity, causing the bridge to collapse and staged a scene that made people laugh and cry.
