Description

technical field

[0001] The invention belongs to the technical field of anti-shock and shock absorption of civil engineering structures, and in particular relates to a composite coupling beam damper and an assembly method thereof. Background technique

[0002] In high-rise and super high-rise buildings, due to the complexity of their structures, the requirements for their seismic performance are relatively high. Shear wall structures or frame shear wall structures are widely used in modern high-rise and super high-rise buildings due to their excellent lateral stiffness and load-bearing capacity. In actual engineering, due to the needs of building functions, it is often necessary to open holes in the wall to form a combined shear wall with connecting beams. According to the seismic requirements of ductility, the coupling beam needs to yield before the wall pier, which consumes a lot of seismic energy. However, the span height of the coupling beam is relatively small, and it i...
