Abstract

The invention discloses a self-resetting double-bow opposite-pull double energy dissipation supporting device. A belleville spring is adopted as a reset system, an arc-shaped steel plate is used as ametal energy dissipation element, in the case of the metal energy dissipation element, the arc-shaped steel plate belongs to a bending yield energy dissipation type, compared with other traditional metal energy dissipation modes, the energy dissipation performance of the arc-shaped steel plate is stable, damaged positions of the element are easy to control, in addition, the arc-shaped steel plateenergy dissipation element is easy to replace after an earthquake, recycling of integral support is realized, the economical and practical requirements are confirmed, and wide popularization is easy;in the case of a reset device, the price of the belleville spring is low, restoring force can be stably provided, and the influence on the temperature, humidity and other external factors is smaller;and no damage and low damage during the earthquake and self-resetting after the earthquake of the supporting device are realized, the structural construction is simple and clear, and the manufacturingand mounting process is simple and convenient.

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...
