Problems solved by technology

Previous earthquake damages have shown that the collapse probability of frame-shear wall structures is usually very small, but once the bottom of the shear wall components is damaged, the maintenance cost is extremely high. For example, in the 2011 Christchurch earthquake in New Zealand, a large number of structures containing No collapse occurred, but due to the severe damage at the bottom of the wall pier, it was forced to demolish and rebuild, resulting in huge economic losses

Abstract

The invention discloses a self-resetting energy-dissipating rocking shear wall, which comprises: a first connecting steel member and a second connecting steel member; a replaceable energy-consuming assembly, and the bottom and top of the replaceable energy-consuming assembly are respectively provided with a first connection The steel member and the second connecting steel member, the replaceable energy dissipation component includes: a plurality of steel columns arranged side by side in the horizontal direction, and the steel columns are connected by bolts to form a whole body that can withstand bending moment and shear force; set On the upper reinforced concrete wall on the second connecting steel member, the upper reinforced concrete wall coordinates with the replaceable energy-dissipating components through the second connecting steel member to resist the lateral action of the earthquake. The shear wall can be restored to its original position after the earthquake, reducing the residual displacement, and the steel columns are connected by bolts, which greatly reduces the difficulty of post-earthquake repair and maintenance cost. The maintenance is convenient and low-cost, and it is popular and simple. accomplish.

Description

technical field [0001] The invention relates to the technical field of civil and structural engineering, in particular to a self-resetting energy-consuming rocking shear wall. Background technique [0002] Related technologies, with the development of the economic level, there are more and more multi-story buildings in cities, and the reinforced concrete frame-shear wall structure has become a widely used multi-story structure. However, when a strong earthquake occurs, the bottom of the shear wall of the reinforced concrete frame-shear wall structure is usually severely damaged due to the huge overturning moment. Since most shear walls are made of cast-in-place concrete, they are extremely difficult to repair and replace. Previous earthquake damages have shown that the collapse probability of frame-shear wall structures is usually very small, but once the bottom of the shear wall components is damaged, the maintenance cost is extremely high. For example, in the 2011 Christc...
