Abstract

The invention discloses a self-resetting double-bow-to-pull double energy-dissipating support device. By adopting a disc spring as a reset system and an arc-shaped steel plate as a metal energy-dissipating element, the arc-shaped steel plate is a curved metal energy-dissipating element. Yield energy dissipation type, compared with other traditional metal energy dissipation forms, its energy dissipation performance is stable, and the damage position of the component is easy to control. In addition, the arc-shaped steel plate energy dissipation element is easy to replace after the earthquake, realizing the reuse of the overall support, which is economical It is easy to widely popularize because of the requirements of safety and practicability; as far as the reset device is concerned, the disc spring is cheap, can provide the restoring force stably, and is less affected by temperature, humidity and other external factors; the invention realizes the support device No damage during earthquake, low damage and self-resetting after earthquake, simple and clear structure, easy manufacturing and installation process.

Description

technical field [0001] The invention relates to the technical field of shock absorption in civil engineering, in particular to a self-resetting double-bow-to-pull double-energy-dissipating support device. Background technique [0002] Introducing braces into the structure to form a traditional anti-lateral force system can greatly increase the lateral stiffness of the structure and improve the seismic performance of the structure, but whether it is conventional braces (Conventional braces, CB) Buckling-restrained braces (BRB) belong to the category of metal damping energy dissipation, and its energy dissipation mechanism is realized through the elastic-plastic deformation of steel, which also leads to the good hysteresis of this energy dissipation form. Despite the advantages of performance and energy dissipation capacity, there are also problems such as excessive residual deformation after the earthquake, accumulation of component damage, and excessive interstory displaceme...
