In view of the large amount of steel and mass of the conventional viscous damping wall, the extrusion of the inner steel plate will cause the viscous damping material to deform by extrusion rather than by pure shearing. The invention utilizes the corrugated sandwich plate to replace a steel plate to form a member of the viscous damping wall so as to reduce the weight of the damping wall. In addition, the tool bit structure at the edge of the inner steel plate is utilized to reduce the extrusion of the edge of the inner steel plate on the viscous damping material, so that the extrusion deformation of the viscous damping material is reduced, and the output characteristic of the viscous damping wall is improved. The structure of the corrugated sandwich steel plate of the side wall of the outer steel box can meet the requirement of local stability, and a stiffening rib is omitted, so that the outer surface is smooth, and the building maintenance design and construction are facilitated.
Examples
Hereinafter, the viscous damping wall of the corrugated sandwich plate of the present invention will be described in detail by way of specific examples.

The top of interior steel sheet 1 is provided with a horizontal roof 11, and interior steel sheet 1 is connected with horizontal roof 11 is perpendicular, and presents "T" type structure in both sides.
Further, a plurality of stiffening ribs are respectively arranged on the front side and the rear side of the upper end part of the inner steel plate 1; meanwhile, in order to ensure that the inner steel plate 1 does not move out of the plane when moving in the horizontal direction, thin steel plates are arranged on the front side and the rear side of the lower part of the inner steel plate 1 to restrain the inner steel plate 1.
Further, the inner steel plate 1 is composed of a corrugated sandwich plate, the corrugated sandwich plate is composed of two thin steel plates sandwiching a corrugated steel plate, the contact part of the corrugated steel plate and the thin steel plates is connected by welding, and the corrugated groove of the corrugated steel plate is arranged along the horizontal direction. Two thin steel plates of the corrugated sandwich plate are respectively folded at the left edge, the lower edge and the right edge of the inner steel plate 1, and the left edge, the lower edge and the right edge of the inner steel plate 1 are respectively welded to form a cutter head.
The outer steel box 2 is a cavity structure with an opening at the upper part, the lower part of the inner steel plate 1 is inserted into the cavity of the outer steel box 2, and a small gap is reserved between the bottom of the inner steel plate 1 and the inner bottom surface of the outer steel box 2 to prevent the contact between the bottom and the outer steel box from generating large friction force.
Further, the front and rear side walls of the outer steel box 2 are composed of two corrugated sandwich plates, and other members are composed of steel plates.
