Embodiment Construction

[0025] Such as Figure 1~4 As shown, a viscoelasticity-mild steel shear type combined energy dissipator 10 includes a viscoelastic damper and a shear energy dissipating composite plate. The shear energy-dissipating composite plate includes a horizontal partition 3, an energy-dissipating web 5, and a connecting end plate 6. The horizontal partition 3 and the connecting end-plate 6 are respectively fixed on the upper and lower ends of the energy-dissipating web 5. In this embodiment, The welding method is fixed. The viscoelastic damper is arranged on the horizontal partition 3 and includes a U-shaped cover 1 and a viscoelastic damping interlayer 2 between the U-shaped cover 1 and the horizontal partition 3 . The viscoelastic damping layer 2 is vulcanized and bonded to the U-shaped cover plate 1 and the horizontal partition plate 3 .

[0026] The length of the U-shaped cover plate 1 is greater than the length of the viscoelastic damping interlayer 2, and surrounds the viscoelas...

Abstract

The invention discloses a viscoelastic-mild steel shear-type combined energy consumer which comprises a viscoelastic damper and a shear energy-consuming combined panel; the shear energy-consuming combined panel comprises a horizontal division board, an energy-consuming web and a connecting end plate; the horizontal division board and the connecting end plate are respectively arranged on the upper end and the lower end of the energy-consuming web fixedly; and the viscoelastic damper is arranged on the horizontal division board, and comprises a U-shaped cover plate and a viscoelastic damping interlayer which is arranged between the U-shaped cover plate and the horizontal division board. The viscoelastic damper and the hear energy-consuming combined panel work collaboratively, the damage to a main structure is reduced by shearing the vibration energy in a hysteresis deformation dissipation input structure, so that the purposes of controlling wind vibration and absorbing shock are achieved simultaneously.

Description

technical field [0001] The invention belongs to the field of construction, and relates to a combined energy dissipator, which can be applied to wind vibration and shock absorption control of civil engineering structures. Background technique [0002] The energy dissipation and vibration reduction of building structures refers to the installation of appropriate energy dissipation components in the building structure. The energy dissipation components can be composed of energy dissipation and vibration reduction devices and supporting components such as diagonal braces, walls, beams or nodes. Viscoelastic damper is a typical passive control device, which can exert vibration control effect without large relative deformation, and can be used for structural earthquake and wind vibration control at the same time. However, due to the limited shear and deformation capabilities of viscoelastic materials, their energy dissipation capabilities are limited, resulting in a large differen...
