The invention relates to a steel tube shear wall for a building, and belongs to the field of building members. The steel tube shear wall is characterized in that the shear wall adopts a rectangular steel tube type structure, a steel bar truss is positioned in a steel tube and is welded with the steel tube together, and an anchor rod is welded on the inner side of the steel tube wall to realize the connection of the steel tube and concrete in the steel tube. The steel tube shear wall for the building has the advantages that the structure is simple, and a steel structural member and a steel concrete combined member have excellent connection performance, and can realize prefabrication production and site assembly and connection of the structural members; therefore, the building is enabled to have excellent seismic restraint performance, the sizes of the structural members are accurate, the quality control is excellent, the building quality is improved, the service life is long, the labor environment of operation personnel is improved to the greatest extent, the construction period is shortened, and the project cost is lowered.
