The invention provides a waveform energy dissipation steel plate coordination type internal and external cylinder damper, and belongs to the field of architectural structure vibration control. The waveform energy dissipation steel plate coordination type internal and external cylinder damper comprises an upper plate, a lower plate, upper plate screw holes, lower plate screw holes, an outer round energy dissipation steel plate, fastening nuts, an inner round energy dissipation steel plate, coordination connecting steel ribs, end energy dissipation steel plates, elastic cementation filling materials, foamed aluminium energy dissipation materials, semicircle waveform energy dissipation steel plate wave crest sections and semicircle waveform energy dissipation steel plate wave trough sections.The waveform energy dissipation steel plate coordination type internal and external cylinder damper has the beneficial effects that the outer round energy dissipation steel plate and the inner roundenergy dissipation steel plate are connected by the coordination connecting steel ribs, and the semicircle waveform energy dissipation steel plate wave crest sections and the semicircle waveform energy dissipation steel plate wave trough sections are arranged to coordinate an inner cylinder and an outer cylinder, guarantee that the inner cylinder and the outer cylinder are close and not far away from each other, and improve the coordinating energy dissipation capacity of the inner cylinder and the outer cylinder; and during application under normal condition, overall rigidity of the architectural structure can be increased, and during an earthquake, earthquake reaction of the architectural structure can be reduced.

Description

technical field [0001] The invention belongs to the field of vibration control of building structures, in particular to a coordinated type inner and outer cylinder damper of corrugated energy-dissipating steel plates. Background technique [0002] Metallic yielding dampers are various forms of damping energy dissipators made of mild steel or other soft metal materials. Metals have good hysteretic properties after yielding, and some metals have elastic-plastic hysteretic deformation energy dissipation, including mild steel dampers, lead dampers, and shape memory alloys (SMA) dampers. The mechanism of its vibration control on the structure is to dissipate part of the energy of the structure vibration through the yield hysteresis energy consumption of the metal, so as to reduce the structural response. The mild steel damper is to make full use of the soft steel after entering the plastic stage Good hysteresis characteristics. In 1972, American scholars such as Kelly and Skinn...

Problems solved by technology

At present, the initial stiffness of many dampers is not large enough, the yield dispersion area of ​​the material is not large enough, and the design of the energy dissipation structure is not very sufficient, so that the energy such as kinetic energy or elastic potential energy of the structure cannot be fully converted into heat energy and dissipated. Many dampers are only It can increase the overall stiffness of the building structure during normal use, but when a large earthquake occurs, many dampers cannot meet the requirements of reducing the seismic response of the building structure
