The invention provides a displacement amplification type multi-stage soft steel energy dissipation self-resetting support. The displacement amplification type multi-stage soft steel energy dissipation self-resetting support comprises two constraint end plates which are symmetrically arranged left and right, wherein a guide rod and two sliding plates which are in sliding fit with the guide rod are arranged between the two constraint end plates, the left end and the right end of an energy dissipation steel plate are hinged to the outer edges of the two sliding plates respectively, and the energy dissipation steel plate is in an arch shape which is bent in the direction away from the axis of the sliding plates; and an elastic resetting system is arranged between the two sliding plates, the outer side of one sliding plate is connected with a loading end, and the loading end penetrates through the constraint end plate close to the sliding plate. The displacement amplification type multi-stage soft steel energy dissipation self-resetting support is convenient to machine and easy to install, can be arranged in a structure as an additional energy dissipation device, and can also be used for post-reinforcement of an existing structure; and a self-resetting and energy dissipation dual system is provided, the energy dissipation device has a displacement amplification function, damping energy dissipation can be generated at a low displacement level, and the damping energy dissipation capacity of the device is improved.
Description
technical field [0001] The invention relates to the technical field of civil and architectural structures, in particular to a displacement-magnifying multi-stage mild steel energy-dissipating self-resetting support. Background technique [0002] Earthquake has become one of the most threatening disasters to human beings among many natural disasters due to its suddenness, unpredictability and strong destructiveness. Strong and destructive earthquakes have caused huge losses to human life, property and natural resources, and hindered social and economic development to a large extent. [0003] Research in recent years has shown that self-resetting energy-dissipating devices, as a new type of load-bearing energy-dissipating component, integrate the dual functions of reset and energy dissipation. It can support the problem of large residual deformation after yielding, and can be used for reinforcement and repair of existing buildings and defense enhancement of new buildings. At...
