Abstract

The invention discloses a punched rib and pull rod constraint double-layer steel plate concrete shear wall. The punched rib and pull rod constraint double-layer steel plate concrete shear wall comprises two opposite wall body steel plates, connection steel plates at the two ends of a wall body, filling concrete defined by the steel plates on the four sides, punched stiffening ribs and pulling rods penetrating through the punched stiffening ribs. The punched stiffening ribs are arranged on the inner side faces of the steel plates and connected through the pulling rods penetrating through holes. The pulling rods comprise the pulling rods in the wall length direction and the pulling rods in the wall thickness direction. The pulling rods in the wall length direction penetrate through the stiffening ribs arranged in the wall length direction and the connection steel plates at the two ends. The pulling rods at the two ends of the wall body in the wall thickness direction penetrate through the stiffening ribs in the wall thickness direction and the two opposite wall body steel plates. The pulling rods at other portions in the wall thickness direction are arranged between every two adjacent stiffening ribs arranged in the wall length direction every other 2-5 stiffening ribs, and are staggered with the pulling rods in the wall thickness direction along the wall height part at proper intervals. The bearing capacity and ductility of the shear wall can be improved.

Description

technical field

[0001] The invention relates to building structures, in particular to a novel double-layer steel plate concrete shear wall constrained by perforated rib tie rods. Background technique

[0002] For high-rise buildings, the control load of building structure design transitions from vertical force to lateral force, and its anti-lateral force system will become the key to engineering design. The traditional anti-lateral force structure can only increase the bearing capacity of the structure by increasing the thickness of the wallboard. When the structure reaches a certain height, the structural wall will be too thick. Too thick walls will not only waste the structural space, but also reduce the construction cost. The process becomes complicated, and the self-weight of the structure will be increased, and the earthquake action will be increased. The concrete with cracks on the outside will also affect the aesthetics of the building, and it will also make it diffic...
