A self-resetting high-strength concrete shear wall and its manufacturing method

Abstract

The invention provides a damage-controllable high-strength concrete shearing wall and a manufacturing method thereof. The damage-controllable high-strength concrete shearing wall comprises a high-strength concrete wall body, frame steel pipes are arranged on the two sides of the high-strength concrete wall body, and the inner sides of the frame steel pipes on the two sides are connected with the high-strength concrete wall body through anti-shearing connecting keys correspondingly; and the frame steel pipes are internally provided with a plurality of ultra-high-strength longitudinal bars, theultra-high-strength longitudinal bars are poured through high-strength concrete to be anchored, and the surfaces of the ultra-high-strength longitudinal bars are coated with anti-rust coatings. When the damage-controllable high-strength concrete shearing wall deforms greatly due to an earthquake or borne large acting force from the outside world, the ultra-high-strength longitudinal bars can be controlled within the elastic stage to deform for energy dissipation, residual deformation of the shearing wall after the earthquake is reduced, the self-reset capacity is provided for the shearing wall, cracking of the concrete can be delayed, a number of large cracks can be prevented from being caused in interfaces between the frame steel pipes and the high-strength concrete wall body, and thus the purposes that damage to a structure after the earthquake is small, and repairing is easy are achieved.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a self-resetting high-strength concrete shear wall and a manufacturing method thereof. Background technique [0002] With the rapid development of construction technology, the height of high-rise buildings is constantly increasing, and the demand is increasing. This type of building needs to bear greater vertical loads and horizontal loads, and has higher requirements for the strength and ductility of building materials. At the same time, the structural form also face new challenges. Due to its advantages of high strength, high deformation modulus, high durability, high fluidity, reduced building weight, and reduced construction cost, high-strength high-performance concrete has developed rapidly in recent years and has also been used in the shear wall structure of multi-story buildings. There are many promotional applications. However, compared with ordinary conc...
