Exterior steel plate and in-fill concrete combined shear wall
The invention provides an exterior steel plate and in-fill concrete combined shear wall which comprises a shear wall exterior mould plate, steel fiber reinforced concrete and normal concrete. The shear wall exterior mould plate is formed by enclosure of exterior steel plate units, the steel fiber reinforced concrete is poured at a bottom reinforcement area of the shear wall exterior mould plate, and the normal concrete is poured in other areas in the shear wall exterior mould plate. The inner surface of the shear wall exterior mould plate is provided with a plurality of rows of stiffening ribs with holes. The steel fiber reinforced concrete replaces normal concrete in the bottom reinforcement area of the shear wall to withstand shearing force jointly with steel plates, so that shear resistance of the bottom of the shear wall is improved. The shear wall exterior mould plate and the concrete are closely coupled by the stiffening ribs with the holes, crack resistance of concrete at the bottom of the shear wall is greatly improved by the steel fiber reinforced concrete, and fatigue resistance and toughness are improved greatly. Therefore, section of a wall body can be reduced under the condition that a structural system of the shear wall meets the requirements on earthquake-proof performance, and application advantages of the shear wall are more evident in the field of high walls.
