Multistage articulated viscous damping wall

Abstract

The invention discloses a multistage articulated viscous damping wall. The multistage articulated viscous damping wall comprises an inner steel plate and is characterized in that the inner steel plate is composed of an upper inner steel plate (15) and a lower inner steel plate (16), the upper inner steel plate (15) and the lower inner steel plate (16) are connected in a relative rotating mode, the inner steel plate is arranged in a box-structure steel box body (7) with the top end opened and the bottom and the side faces closed, the top end of the inner steel plate stretches out of the top end opening of the steel box body (7), the bottom end of the steel box body (7) is rigidly connected with a lower connecting plate (1), top stretch-out steel plates (13) perpendicularly stretching out for a certain distance are arranged on the peripheral edges of the top end opening of the steel box body (7), and a top sealing plate is arranged at the top end of the inner steel plate. The problem of deforming of the inner steel plate is reduced, and energy dissipating capacity of the damping wall is enhanced; when face external face is generated, rotating deformation of the inner steel plate will not be generated; the stability and the fire resistance of the damping wall are enhanced.

Description

technical field [0001] The invention relates to the anti-seismic field of building engineering structures, in particular to a multi-segment hinged viscous damping wall. Background technique [0002] The main idea of ​​energy dissipation and shock absorption technology is to set energy dissipation components in some parts of the structure with large deformation, or directly set some components (such as coupling beams) as energy dissipation components, under the action of earthquake load or wind load , these energy-dissipating components can quickly enter the energy-dissipating state, consume part or most of the energy input into the structure by external loads, thereby reducing the dynamic response of the main body of the structure, and avoiding or greatly reducing the possibility of damage to the main body of the structure. [0003] The viscous damping wall is a new type of damping element used for energy dissipation and shock absorption of building structures. Such as fig...
