Cause of accident in Taiyuan Follette Hotel

1. First of all, the top floor of Taiyuan Follette Hotel was covered with a layer of colored steel, but the precast slab on the top floor was not a load-bearing slab, so it was not replaced when it was covered.

2. Secondly, Follette Hotel in Taiyuan was not sufficiently reinforced when covered with color steel layer, so that the shaking of color steel layer caused the lower wall to move under the action of wind, which made the pressure wall of precast slab slip.
