Tower top force transfer structure for concrete filled steel tube combined tower

The invention relates to the technical field of bridge engineering, in particular to a tower top force transmission structure for a concrete filled steel tube combined tower, which comprises a force transmission shell, the force transmission shell comprises a horizontal bearing plate and a vertical coaming, the horizontal bearing plate is used for being arranged at the tops of all tower columns, and the vertical coaming is arranged on one side, far away from the tower columns, of the horizontal bearing plate and is arranged along the circumferential direction of the horizontal bearing plate; the force transmission shell is used for defining a containing cavity, the containing cavity is used for being filled with concrete, and the force transmission shell and the concrete act synergistically to transmit loads. The first stiffening structure is arranged in the containing cavity and connected with the horizontal bearing plate and the vertical surrounding plate. The second stiffening structure is arranged on the
