Jacket of offshore wind turbine generator considering failure safety design

The utility model relates to the technical field of jackets of offshore wind turbine generators, in particular to a jacket of an offshore wind turbine generator considering failure safety design, and aims to solve the problem that the jacket of the existing offshore wind turbine generator is easy to collapse quickly due to damage of a longitudinal beam. In order to achieve the purpose, the jacket comprises at least three longitudinal beams which are evenly distributed around the central axis of the jacket, the axes of the longitudinal beams and the central axis are coplanar, and every two adjacent longitudinal beams are connected through a transverse rod at the first height position. The part, below the first height position and the part, above the second height position, of every two adjacent longitudinal beams are connected through a plurality of cross rods which are uniformly distributed up and down; every two adjacent longitudinal beams in the area between the first height position and the second height p
