This invention relates to a high-rise structure energy dissipation and vibration reduction system based on a rotational variable friction damper and its operation method. The system includes frame columns, a core tube, a chain rod assembly, and friction energy dissipation components. This invention amplifies the minute displacements generated by the core tube through the chain rod assembly, thereby enabling the friction energy dissipation components to function effectively.
