Description

Modular assembly combined steel plate shear wall with replaceable core module

technical field

The invention relates to a shear wall, in particular to a modular assembly steel plate shear wall with replaceable core modules.

Background technique

Shear wall structure is a kind of anti-lateral force system against horizontal load. Under the earthquake, the shear wall not only bears most of the seismic shear force, but also plays an important role in dissipating the seismic energy. In the shear wall structure system, frame-core tube structure system and inner tube-outer frame tube structure system widely used in high-rise buildings, the shear wall mostly appears in the form of combined shear wall. Combined shear wall is a kind of anti-lateral force system that combines two or more shear walls to resist horizontal load through connecting beams; the way of resisting horizontal force is changed from only relying on the bending resistance of the solid shear wall section to The force couple composed of the bending resistance of each wall pier and the axial force of the wall pier is jointly completed. The lateral stiffness of the combined shear wall is much greater than the sum of the lateral stiffness of each independent wall. Reinforced concrete coupling beams generally have a small span-to-height ratio, and are prone to shear failure under the reciprocating action of earthquakes. At the same time, due to the heavy weight of the entire steel coupling beam in high-rise buildings and the large plastic deformation under strong earthquakes, steel beams and beams are prone to occur. Partial damage occurred at the connection part of the wall pier, and it was difficult to directly replace it after the earthquake. It was very difficult to repair the steel coupling beam after the earthquake. The traditional replaceable coupling beam usually adopts the form of steel coupling beam for the full length, but there are problems such as difficult connection between the steel coupling beam and the shear wall wall, long anchorage length and complex joint design, so the construction process of the shear wall is cumbersome , The problem of inconvenient installation of the internal frame structure of the shear wall.
