Built-in steel plate and concrete composite shear wall
The invention provides a built-in steel plate and concrete composite shear wall which comprises a built-in steel plate. A plurality of rows of stiffening ribs with holes are arranged on two sides of the built-in steel plate, and end columns are arranged at two ends of the built-in steel plate; steel fiber reinforced concrete wraps bottom reinforcement regions of the built-in steel plate and the stiffening ribs with the holes, and normal concrete wraps other regions of the built-in steel plate and the stiffening ribs with the holes. The built-in steel plate and concrete composite shear wall has the advantages that shear force on the bottom reinforcement regions of the shear wall can be resisted by the steel fiber reinforced concrete instead of being jointly resisted by the normal concrete and the built-in steel plate, and accordingly the shear bearing capacity of the bottom of the wall can be improved; the built-in steel plate and the concrete are closely coupled with each other by the aid of the stiffening ribs with the holes, the crack resistance and the fatigue resistance of the concrete in the bottom reinforcement regions of the shear wall can be obviously improved by the steel fiber reinforced concrete, the toughness of the concrete in the bottom reinforcement regions of the shear wall can be improved to a great extent, accordingly, the section of a wall body can be advantageously diminished under the condition that requirements on the seismic performance of a shear wall structure system are met, and the built-in steel plate and concrete composite shear wall is obvious in superiority of application to high walls.
