Scissor-type deformation amplifying device for amplifying energy consumption effect of damper

Abstract

The invention relates to a scissor-type deformation amplifying device for amplifying the energy consumption effect of a damper. The device is arranged in a framework composed of a left structural column, a right structural column, an upper beam and a lower beam; the device comprises a damper, a first support, a second support, a third support, a fourth support, a cover plate and an instability prevention plate, wherein the upper end of the cover plate is welded below the first support and the second support, the middle part of the cover plate is hinged with two ends of the damper through movable shafts, the lower end of the cover plate is welded together with the upper end of the instability prevention plate, and the lower end of the instability prevention plate is welded together with the third support and the fourth support. Compared with the prior art, the scissor-type deformation amplifying device has the advantages that the displacement of the damper can be amplified to more than 2 times of the inter-story displacement, the energy consumption of the damper can be increased, and the additional damping ratio of the structure under the actions of wind load and earthquake can be increased; in addition, the out-of-plane stability of the device, caused under the action of rare occurrence earthquake, is avoided by using a construction measure, and the safety of the structure under the action of the rare occurrence earthquake is ensured.

Description

technical field [0001] The invention relates to a device for amplifying the energy consumption effect of a damper, in particular to a scissor-type deformation amplifying device for amplifying the energy consumption effect of a damper. Background technique [0002] Energy dissipation and shock absorption technology is one of the mature high-tech technologies that are widely promoted and applied in the world's earthquake engineering circles. [0003] Dampers have been widely used in building structures and bridges as energy dissipation and shock absorption products, and have made important contributions to ensuring the safety of people's lives and properties. However, since the damper can only exert a good energy dissipation effect under a large displacement, the current damper is mostly used in the shear wall, frame tube and other structures with small displacement, which cannot achieve satisfactory results. The application of dampers in these structures is restricted. [0...

Problems solved by technology

However, since no special structural measures are taken to prevent out-of-plane instability of the device, under the action of rare earthquakes, the structural deformation is large, which may cause excessive damping force, out-of-plane instability of the device, and the two ends of the damper cannot reach the expected The relative displacement and the energy consumption of the damper are smaller than expected, causing the structure to fail to meet the design performance goals and severely damaged under the action of rare earthquakes
