The wall piers were coupled by vertical metallic yielding dampers in the preset slits of coupling beams in the damping-coupled wall structure system, and the system’s basic structural forms and theory were as follows: cut off the coupling beams at their mid-spans and then connect the separated wall piers by vertically installed metallic yielding dampers. Therefore, the relative vertical dislocations between adjacent wall piers could motivate the dampers to dissipate seismic energy during earthquakes and thus the wall piers could be protected from severe damage. The nonlinear seismic responses of the damped wall were evaluated by modeling wall piers and coupling beams with macro beam elements, i.e., the fiber-section model with shear behavior, and dampers with link elements; the dimensionless parameters of dampers were chosen as key variables to execute seismic analysis and parametric studies. A series of static and dynamic nonlinear analysis cases were performed with regard to dimensionless parameters variation, and results indicates that the seismic responses of the damping-coupled wall can be well controlled with less cracks and damage compared with the conventional wall with a proper set of damping parameters. In brief, the proposed damping-coupled wall provides better seismic performance. Besides, the intensity, spectrum characteristics of seismic excitations and the distribution modes of dampers can both exert some influences on the seismic performance of a damping-coupled wall. Based on the analytical results, some recommendations are provided for the design of a damping-coupled wall.
