Yield-adjustable X-brace energy dissipation device
The invention discloses a yield-adjustable X-brace energy dissipation device. Core energy dissipation component sets of the energy dissipation device comprise four energy dissipation steel plate bars and are divided into a first-stage energy dissipation component set and a second-stage energy dissipation component set. The two ends of each energy dissipation steel plate bar are hinged to lug plates fixed to a top plate or bottom plate. In the second-stage energy dissipation component set, the lug plate connected with one end of each energy dissipation steel plate bar is provided with a horizontal strip-shaped groove, and one end of each energy dissipation steel plate bar can slide in the corresponding horizontal strip-shaped groove through a pin. When relative displacement of the upper bottom plate and the lower bottom plate is not large, the first-stage energy dissipation steel plate bars work firstly; when the relative displacement increases and reaches preset target displacement, the pins of the second-stage energy dissipation steel plate bars are in a pressing state, tensile deformation starts to be generated, and energy dissipation is yielded. The displacement in which the second-stage energy dissipation steel plate bars start yield energy dissipation is controlled through control over the lengths of the sliding grooves. The requirements for energy dissipation and shock absorbing of engineering structures in small earthquakes and large earthquakes are met at the same time, and earthquake energy is dissipated in stages.
