Novel friction-viscous damping wall

Abstract

The invention provides a novel friction-viscous damping wall which comprises a friction assembly, an inner shear plate and an outer steel box. The friction assembly comprises an upper friction connecting plate, a lower friction connecting plate and an energy dissipation friction piece arranged between the upper and lower friction connecting plates. A plurality of long-elliptical shaped bolt holesare evenly distributed in the upper and lower friction connecting plates, and a plurality of circular bolt holes are evenly distributed in the energy dissipation friction piece. The top end of the inner shear plate is connected with the lower friction connecting plate. The inner shear plate is vertically inserted into a damping groove, and the damping groove is filled with viscous materials. By introducing the energy dissipation principle of a friction type damper, displacement related and speed related dampers are formed, the bearing capacity of a damping wall is defined within the preset bearing capacity range, the phenomenon that the large bearing capacity is caused by uncertainty of seismic waves is avoided, meanwhile, the dependency of the damping wall on the structure frequency is avoided, the energy dissipation capacity of the damping wall is stabilized, and the good damping effect is achieved.

Description

technical field [0001] The invention relates to a damping wall, in particular to a novel friction-viscosity damping wall. Background technique [0002] Viscous damping walls are widely used as shock-absorbing devices for building structures. They are generally composed of external steel boxes, internal energy-dissipating shear steel plates and high-damping viscous materials. Among them, the external steel box is fixed on the top of the bottom beam of the floor through the connector, and the internal energy-dissipating shear steel plate is fixed on the bottom of the floor top beam through the connector. When the floor generates relative deformation (or relative speed), the energy-dissipating shear steel plate and The high-damping viscous material in the gap between the outer steel boxes produces a velocity gradient, and then the internal friction of the viscous material dissipates the seismic energy while generating a large damping force.
