The invention discloses a segmented prestress self-resetting damage concentration prefabricated swing shear wall which comprises a plurality of wall bodies arranged from bottom to top, wherein damage concentration blocks are arranged at the corners of the wall bodies. Each wall body is internally provided with unbonded prestressed steel bars, wherein one end of each unbonded prestressed steel bar is anchored in the wall body, and the other end of the unbonded prestressed steel bar stretches out of the upper portion of the wall body. Each wall body is provided with reserved prestressed steel bar ducts. Anchorage devices are arranged at the upper ends of the reserved prestressed steel bar ducts. According to every two adjacent wall bodies, the reserved prestressed steel bar ducts located in the upper wall body correspond to the unbonded prestressed steel bars arranged in the lower wall body, and after the unbonded prestressed steel bars penetrate through the corresponding reserved prestressed steel bar ducts, the upper ends of the unbonded prestressed steel bars are anchored through the anchorage devices. The prestress is applied in a segmented mode, the construction difficulty is lowered, the redundancy rate is increased, the situation that the overall structure is damaged due to prestress failure in a certain position is avoided, the structure rigidity can be reduced through swinging, lifting, falling and impacting of the wall bodies in an earthquake, the structural cycle is shortened, and the earthquake action is reduced; and meanwhile, the self-resetting function is achieved.
