Problems solved by technology

After theoretical analysis and experimental research by many scholars at home and abroad, it is confirmed that the mild steel damper has stable hysteresis characteristics, good low-cycle fatigue performance, long-term reliability and is not affected by the environment and temperature. It is a very good damper. Promising energy consumers, all-metal dampers have the advantages of large recoverable deformation, strong damping capacity, durability, corrosion resistance, fatigue resistance, wide operating temperature range and low maintenance costs, and are transmitted to building structures due to earthquakes and other reasons The external energy of the structure is the source of the vibration of the structure, so the energy dissipation properties of the damper will be the key to reducing the vibration response of the structure. Anti-buckling effect, resulting in a significant reduction in energy dissipation capacity

Abstract

The invention belongs to the field of vibration control of a building structure, particularly relates to a multi-directional shock-absorbing buffering multi-order energy-consuming damper. The multi-directional shock-absorbing buffering multi-order energy-consuming damper comprises an upper plate, a lower plate, a screw hole A, a screw hole B, an energy-consuming steel plate A, an energy-consumingsteel plate B, an elliptical hole, a coordinating and connecting steel bar, an energy-consuming rib, a horizontal arc-shaped energy-consuming steel plate, a foaming aluminum energy absorbing plate, afoaming aluminum energy-consuming material, a locking nut, a circular soft steel energy-consuming internal cylinder, a end portion energy-consuming steel plate, a horizontal energy-consuming separating soft steel plate, a vertical energy-consuming separating soft steel plate, an energy-consuming side steel plate and a vertical arc-shaped energy-consuming steel plate. The multi-directional shock-absorbing buffering multi-order energy-consuming damper is of a structure enclosed by the upper plate, the lower plate, the energy-consuming steel plate B and the energy-consuming side steel plate. Thefoaming aluminum energy-consuming plate is arranged at the position, close to the energy-consuming steel plate B, of the inner of the enclosed structure. The multi-directional shock-absorbing buffering multi-order energy-consuming damper has the advantage and beneficial effect that the earthquake response of a building structure is reduced by using the structural design of multi-directional shockabsorption and multi-order energy consumption.

Description

technical field [0001] The invention belongs to the field of vibration control of building structures, in particular to a multi-directional damping and buffering energy consumption damper in stages. 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 Skinner first began to s...
