Background
The reinforced concrete wall is widely applied to high-rise buildings in China as an important component for resisting earthquake. The seismic damage investigation of the past shows that when the aspect ratio of the reinforced concrete wall is less than 2, the wall is easily subjected to brittle shear failure, and the seismic energy consumption resistance of the structure is seriously influenced. In view of this, the inventor proposes to adopt a parting form to divide the reinforced concrete wall body with the aspect ratio less than 2 into a series of single components with the aspect ratio more than 2, so that the single components can be subjected to shearing failure under the action of an earthquake, and the energy consumption capability of the whole wall body is improved through the plastic energy consumption of the single components subjected to bending failure. However, after the reinforced concrete wall body is slotted, on one hand, the bearing capacity and rigidity of the wall body are obviously reduced in the using stage, and the bearing capacity and rigidity are seriously degraded under the action of an earthquake; on the other hand, the traditional open seam form also causes the problems of easy cracking, water resistance, high decoration difficulty and the like in the use stage of the wall seam. In addition, the energy consumption of the traditional parting wall mainly depends on the self energy consumption of the wall body of the parting shear wall, and the energy consumption capacity is limited.
