What caused the collapse of a hotel in Linfen, Shanxi?

The collapse of a hotel in Linfen, Shanxi Province occurred at 9 am on August 29 this year. At that time, Juxian Hotel in Chenzhuang Village, Taosi Township, Xiangfen County, Linfen City was holding a party. A * * *, more than 50 people, a small part gathered on the first floor, most of them on the second floor. Due to too many people on the second floor, some floors cracked and collapsed due to excessive load, resulting in a large area of floor collapse. Most people on the second floor fell and the injuries were relatively minor. Many people were hit by the collapsed concrete floor on the first floor, and the casualties were a bit heavy.

After the incident, the fire brigade and other rescue organizations urgently dispatched more than 20 large-scale rescue equipment vehicles, ambulances 15, medical staff 100 and 840 related rescue teams to the Juxian Hotel in Linfen, Shanxi Province to organize rescue activities. By that afternoon, * * * had rescued 45 people, of whom 17 were killed, 7 were seriously injured and 2 1 was slightly injured. The rest of the rescue work is still in progress. The Shanxi Provincial Party Committee and the provincial government issued instructions to rescue the trapped people at all costs and seize every opportunity to rescue the trapped people.

There are several reasons for the accident: first, the hotel was built more than ten years ago, and the original building was a single-story brick masonry structure, which may not have structural columns and ring beams, resulting in its limited bearing capacity; The second reason is that the flat roof panel may be a solid non-prestressed precast slab with relatively low local price, or it may be a cast-in-place thin plate when building this house; Third, even the diameter of steel bars in the floor is smaller than the conventional one, and the reinforcement is obviously insufficient; Fourthly, a few years ago, in order to expand its scale, this hotel built a second floor with a steel structure on the first floor, transforming the original non-owner roof on the first floor into the second floor, where people can go. The dead load of two-story steel structure residence is completely ignored.

For these places where many people will gather, we must implement safety production. In particular, hotels and crowded places, whether newly built or rebuilt, should be built in strict accordance with the requirements. They should never choose inferior materials because they want to be cheap, and they will regret it once something happens.
