Abstract

The invention discloses a metal shearing type damper structure form. The metal shearing type damper structure form comprises a core plate lower end special-shaped connecting section, a middle sectionenergy consumption section capable of controlling a core plate to be reasonable in slenderness ratio, a core plate upper end special-shaped connecting section and flange plates on the two sides, the upper section, the middle section and the lower section of the core plate are formed by integrally machining a mild steel plate, it is guaranteed that steel performance of the energy consumption section is fully exerted, and stress is reasonably transmitted. Under the same load, the size, the weight and the manufacturing cost of a damper are greatly reduced, accurate simulation can be carried out through numerical simulation, consistency of damper unit parameters in an actual product and the overall structural design is kept, and the metal shearing type damper structure form is wide in application range, efficient and reliable.

Description

Technical field: [0001] The invention relates to the field of construction engineering, and relates to a metal shear damper among metal dampers. Background technique: [0002] In order to control the dynamic response of building structures, especially high-rise building structures, under wind load and earthquake load, some mechanical devices are often used to dissipate wind vibration and earthquake action and introduce energy-consuming components to protect the main load-bearing components. This is energy dissipation and shock absorption technology. Applications in building structures. Metal shear type steel plate dampers have stable energy dissipation capability and low sensitivity to the frequency of external force, and are widely used in construction projects to improve the safety performance of buildings under large earthquakes. At present, the traditional metal shear damper pays more attention to improving the material performance and improving the fatigue performance ...
