Coupling beam is crucial to the seismic performance of the shear wall structure. When the coupling beam has enough ductility, there will be cracks on the section and plastic hinges will appear under earthquake, which will absorb a large amount of seismic energy. The coupling beam plays an important role in reducing the force inside the shear wall and delaying the yield of the shear wall. At the same time, the plastic hinge still transfers the bending moment and shear force, therefore, to act as a certain constraint on the shear wall to help the shear wall to maintain enough stiffness and strength. Among them, the replaceable coupling beam can help the recovery of structural performance, with great advantages and application prospects. This paper mainly summarizes the research progress of replaceable coupling beam, and analyzes its advantages and disadvantages.
