Abstract

The invention provides a composite coupling beam damper and an assembling method thereof. The damper comprises a viscoelastic damper and further comprises an SMA damper and a reset friction damper, the SMA damper is connected to one end of the viscoelastic damper in parallel, and the reset friction damper is connected to the other end of the viscoelastic damper in series; and during assembly, a front constraint plate, a rear constraint plate, a friction damping shear plate, a viscoelastic damping shear plate, an upper baffle, a lower baffle, an outer constraint plate and the like are manufactured firstly, then the reset friction damper is assembled, and then the SMA damper is assembled to complete the assembly method. According to the composite coupling beam damper, the working mode that the viscoelastic damper and the SMA damper are firstly connected in parallel and then connected with the reset friction damper in series is adopted, the advantages of the dampers can be exerted at thesame time, and the defects can be overcome.

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...
