Self-resetting slotted shear wall with global energy consumption mechanism and resetting method
The invention discloses a self-resetting slotted shear wall with a global energy consumption mechanism and a resetting method. The slotted shear wall comprises a shear wall body, wherein vertical slits are formed in the shear wall body to form a plurality of wall limbs; energy-consuming shear-resistant parts are connected between the adjacent wall limbs, and energy generated by mutual dislocation between the adjacent wall limbs is consumed by utilizing shear displacement energy consumption in an earthquake; and the bottom of the shear wall body is connected with the top of a building foundation in an inserted mode to transmit horizontal force, and the shear wall body is connected with the building foundation through an automatic resetting mechanism and used for transmitting overall anti-overturning moment in the earthquake. In the earthquake, the energy-consuming shear-resistant parts start to consume energy through mutual dislocation between the wall limbs when the wall limbs are subjected to small deformation, and when the earthquake is large, the whole wall body rotates to drive the resetting parts to start to consume energy, so that the global energy consumption mechanism is achieved, and the situation that the energy-consuming shear-resistant parts are damaged by excessive displacement in the large earthquake is avoided. The width-to-thickness ratio of all the wall limbs of the shear wall body does not exceed 3, so that the ductility of bending deformation of the shear wall body is fully exerted, and the shear deformation ratio of a traditional shear wall is reduced.
本发明公开了一种具有全域耗能机制的自复位开缝剪力墙及复位方法，开缝剪力墙包括剪力墙体，剪力墙体上开设有竖直缝形成多个墙肢；耗能抗剪部连接于相邻墙肢之间，地震中利用剪切位移耗能，消耗相邻墙肢之间由于相互错动产生的能量；剪力墙体底部与建筑基础顶部插接传递水平力，且通过自动复位机构连接，用于在地震中传递整体抗倾覆力矩。地震中耗能抗剪部在墙肢发生小变形时靠墙肢之间相互错动开始耗能，当受到较大地震时，墙体整体发生转动驱动复位部件开始耗能，以实现全域耗能机制，并且避免了较大地震时耗能抗剪部遭受过大位移的损伤。抗剪墙体各部分墙肢应保证宽厚比不超过3，以充分发挥其弯曲变形的延性，减轻传统剪力墙的剪切变形占比。
