Double-piston variable-order viscous self-restraint steel plate energy dissipation wall
The invention discloses a double-piston variable-order viscous self-restraint steel plate energy dissipation wall, relates to the technical field of structural seismic mitigation and isolation, and aims to solve the technical problem that rigidity and damping of an existing energy dissipation wall are inconvenient to consider when the existing energy dissipation wall encounters an earthquake. Comprising edge columns, self-restraining steel plates, pin shafts, double-piston variable-order viscous dampers, gusset plate lug plates, connecting steel supporting tripods, tripod gusset plates, stiffening ribs and outer frame beams, the self-restraining steel plates are corrugated steel plates, the damping force of the double-piston variable-order viscous dampers is related to the speed during small earthquakes and medium earthquakes, and the damping force is not changed after the medium earthquakes are exceeded; the double pistons are arranged in the double-piston variable-order viscous damper, the sizes of piston cavities can be increased under the condition that the same damping force is guaranteed through the double pistons, internal pressure caused by temperature is reduced, the diameter of the damper under the same damping force can be reduced, and the double-piston variable-order viscous damper is provided with the pressure release valves on the double pistons. The structure has the advantages that rigidity and damping are both considered, and the structure safety is improved.
