The shear walls are connected by the end plates via high-strength binding stay bolts. The stiffness enhancing zone includes a plurality of steel plates and buckling-restrained plates which are respectively arranged on two sides of adjacent steel plates and are connected to the steel plates via bolts. A gap is provided between the adjacent steel plates. The stiffness enhancing zone is provided with a threshold control device. The assembled energy dissipator realizes a reliable lateral bolt connection of shear wall components, and is easy to be assembled and disassembled. The present invention adopts a configuration that the steel plates of the energy-dissipating zone are arranged outside and the steel plates of the stiffness enhancing zone are arranged inside. Under a small or moderate earthquakes, the mild steel of the damper yields to dissipate energy while the steel plates in the enhancing zone are not required to work. When a strong or super strong earthquake occurs, the steel plates in the enhancing zone begins to work to enhance the structural performance. 11854774_1 (GHMatters) P112366.AU
