The purpose of structural seismic response processed mitigates the degree of injury of main structure.
Mild steel damper is passively consumed energy using one kind made of the feature that mild steel yielding intensity is low, plastic deformation ability is strong
Device.Mild steel damper is generally divided into 4 kinds by Energy Dissipation Mechanism: in axial surrender energy consumption, out-of-plane bending energy consumption, shear energy dissipation and face
Bending energy-wasting.Axial surrender energy-consumption damper mainly coheres supporting form using nothing.Out-of-plane bending energy-consumption damper is mainly benefit
Energy consumption is realized with the characteristic surrendered simultaneously at equal thickness outside steel plain, this damper mainly uses X-shaped, triangle and water chestnut
Shape punches, and deformability is strong, and Hysteresis Behavior is stablized, but its initial stiffness is smaller.Shear energy dissipation damper utilizes the shearing of steel plate
Deformation is consumed energy, and effectively improves initial stiffness, but local yielding easily causes stress to be concentrated.
That there are weld seams is intensive for traditional mild steel damper, middle steel plate is easy sheared destruction and out-of-plane buckling destroys etc. lacks
Point reduces the damping energy consumption effect of damper.
