A self-resetting slotted shear wall with global energy consumption mechanism and its resetting method

Abstract

The invention discloses a self-resetting slotted shear wall with a global energy consumption mechanism and a reset method. The slotted shear wall includes a shear wall, and vertical seams are formed on the shear wall to form a plurality of wall members; The energy-dissipating shear section is connected between adjacent wall piers. During an earthquake, the shear displacement is used to dissipate energy and consume the energy generated by the mutual displacement between adjacent wall piers; the bottom of the shear wall is plugged and transmitted to the top of the building foundation. Horizontal force, connected by an automatic reset mechanism, is used to transfer the overall anti-overturning moment in an earthquake. During the earthquake, the energy-dissipating anti-shear part starts to consume energy when the wall limbs are shifted against each other when there is a small deformation of the wall limbs. When it is subjected to a large earthquake, the whole wall rotates and drives the reset part to start consuming energy, so as to realize global energy consumption. mechanism, and avoid the damage of excessive displacement of the energy-consuming shear parts during large earthquakes. The wall pier of each part of the shear wall should ensure that the width-to-thickness ratio does not exceed 3, so as to give full play to its ductility in bending deformation and reduce the proportion of shear deformation of traditional shear walls.

Description

technical field [0001] The invention relates to the field of building technology, and more specifically relates to a self-resetting slotted shear wall with a global energy consumption mechanism and a resetting method. Background technique [0002] High-rise buildings are widely used in my country. Previous earthquake damage shows that the earthquake damage of high-rise buildings is concentrated on the bottom of the main lateral force-resisting member—the shear wall. It is difficult to repair after the earthquake, which affects the use function of the whole building and causes huge economic losses. [0003] The traditional methods to improve the seismic performance of shear walls are as follows: first, divide the wall into two parts vertically, and install steel plate dampers in the middle, but the bottom of the wall plinth is still fixed to the foundation, and the damage to the bottom of the wall due to the overturning moment cannot be avoided. The energy dissipation capacit...

Problems solved by technology

[0005] For this reason, an object of the present invention is to propose a self-resetting slotted shear wall with a global energy dissipation mechanism, so as to solve the problem that the energy dissipation components of the shear wall in the prior art cannot be used in small earthquakes, moderate earthquakes and large earthquakes at the same time. All can play the role of energy consumption, and there is no need to repair the technical problems that can be self-reset after the earthquake
