Swinging wall and swinging wall-frame structure

Abstract

The invention discloses a swing wall and a swing wall-frame structure, and relates to the technical field of swing wall structures. The swing wall comprises a swing wall body and a basic unit. The end face of the swing wall body is provided with a first arc piece. The basic unit is connected with the swing wall body, and a second arc piece is arranged on the end face of the basic unit; any one of the first arc piece and the second arc piece is an arc bulge, and the other one is an arc groove; the arc protrusion and the arc groove formed by the first arc piece and the second arc piece can rotate in a matched mode. According to the swing wall, for an external swing wall-frame structure, the self weight of the wall body can be transmitted to a lower foundation through a large contact surface. The hinged position is not located in the middle of the wall any more, in the swinging deformation process, the dead weight of the wall generates large restoring torque, and structural seismic resistance is facilitated. For an embedded swing wall-frame structure, the problem of stress concentration is solved compared with a traditional swing wall corner which is converted from line contact to surface contact in the swing deformation process.

Description

technical field [0001] The invention relates to the technical field of swing wall structures, in particular to a swing wall and a swing wall-frame structure. Background technique [0002] With the development of anti-seismic technology of building structures, the rapid restoration of functional capabilities of building structures after earthquakes has begun to attract the attention of the engineering community. Among them, the combination of the swing wall and the frame structure can form a relatively typical recoverable functional structure system, the swing wall-frame structure system. At this stage, there are mainly two combinations of swinging walls and frame structures. A rigid swing wall with the same overall height as the frame structure is set, and the swing wall is independent of the frame structure, and the two are only connected by rigid connecting rods that can transmit horizontal forces. Under horizontal seismic loads, the frame structure deforms cooperatively...

AI Technical Summary

Problems solved by technology

The hinged position in this method needs to independently bear the self-weight of the swing wall, and the cost of the hinged structure is relatively high

For the embedded swing wall-frame structure, pre-embedded steel members at the corners or elastic rubber pads are often used to protect the corners of the swing walls. This method can only relieve the compression damage of the corners of the swing walls, and the cost of construction measures is relatively high.
