A factory building in Longhai, Zhangzhou was blown down. How strong is the wind?

Longhai area in Zhangzhou, Fujian Province was hit by a severe typhoon. When the typhoon landed, a factory building in this area was blown down in the strong wind, which shocked many people, especially those who had never experienced a typhoon in mainland China. This is unimaginable, so people want to know how windy it was. According to meteorologists, the wind was 12. Let me introduce some related problems to you.

1. Why are factories easily blown down by typhoons?

Generally speaking, factories are mostly frame structures, which are quite different from traditional reinforced concrete masonry structures. The building materials used are not very strong in typhoon resistance, so when the typhoon crosses the border, it will cause very serious damage to the frame structure factory building. Therefore, in typhoon-prone areas, the construction of production workshops in the factory area needs to be designed in combination with typhoon prevention. If designers don't consider this, the consequences will be very serious. In Fujian coastal areas, industrial buildings generally pay great attention to this point.

2. 12 How bad is the typhoon?

In terms of speed, the speed of typhoon 12 is between 32-4 1 m per second, and it moves very fast, so it can destroy many buildings on the ground and roll people and animals into the air when passing by. It can be said that the crossing is a mess. At this time, if people can't stay in solid buildings or basements, they will face great danger. It is because the wind is too strong that the factory building will be blown down. In fact, it is not necessarily that typhoon prevention was not considered in the process of factory building construction, but that the typhoon level was too high and exceeded the highest intensity of architectural design, so it was blown down, so this problem must be paid attention to.

The occurrence of this incident also puts forward new requirements for the future plant design. Problems related to typhoon prevention must be considered, otherwise it will be difficult to cope with extreme weather, and it will also cause huge economic losses to the users of the factory.
