This utility model belongs to the technical field of reinforced concrete composite shear wall building structures in civil engineering, specifically relating to a bidirectional hollow slab composite shear wall with opening-narrowing stirrups. By setting opening-narrowing stirrups corresponding to the horizontal holes of the bidirectional hollow slab at the edge members at both ends of the shear wall, and by setting longitudinal reinforcement distributed within the wall and longitudinal reinforcement of the edge members at the corresponding positions of the vertical holes of the bidirectional hollow slab and the opening-narrowing stirrups, the structure not only meets design requirements and facilitates construction, but also, due to the special structure of the opening-narrowing stirrups, the constraint area of the opening-narrowing stirrups on the core concrete can be adjusted by the angle formed by the longitudinal and horizontal sections. This allows the constraint effect of the opening-narrowing stirrups on the core concrete to gradually decrease towards the opening end, forming a vertical energy dissipation zone under large horizontal lateral displacement.
