Tuned mass damping device suitable for plate-column node

The invention relates to a tuned mass damping device suitable for a plate-column node, which is adjustable in mass/rigidity/damping, and belongs to the technical field of structural vibration control. Comprising a mass unit, a fixed end component arranged at one end of the mass unit, and a rigidity unit and a damping unit which are arranged between the mass unit and the fixed end component; the tuned mass damping device further comprises a bottom plate connected with the fixed end component, a plate-column node connecting piece and a sliding rail system arranged between the bottom plate and the mass unit. And the plate-column node connecting piece is connected with the bottom plate and is arranged at the other end of the mass unit. The problems of construction difficulty of a TMD system for floor reconstruction and large additional bending moment easily generated by the quality of the TMD system to a column end can be effectively solved, and meanwhile the problems of workflow liquid and the like of a traditio
