Assembled energy dissipator with variable stiffness for lateral connection of shear walls
The present invention relates to seismic resistances of buildings, and more particularly to an assembled energy dissipator with variable stiffness for lateral connection of shear walls, including an energy-dissipating zone, a stiffness enhancing zone and end plates for connecting shear walls. 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
