Multi-dimensional vibration isolation and damping device with anti-drawing performance and vibration isolation and damping method thereof

Abstract

The invention discloses a multi-dimensional vibration isolation and damping device with the anti-drawing performance and a vibration isolation and damping method thereof. The multi-dimensional vibration isolation and damping device comprises an upper pressure-bearing steel plate, a lower pressure-bearing steel plate and other parts such as pre-pressing type cylindrical dampers and a core damping pad, wherein the parts such as the pre-pressing type cylindrical dampers and the core damping pad are disposed between the upper pressure-bearing steel plate and the lower pressure-bearing steel plate.According to the multi-dimensional vibration isolation and damping device with the anti-drawing performance, the pre-pressing type cylindrical dampers distributed on the periphery of the vibration isolation and damping device can weaken the vibration effect in the vertical direction, the core damping pad disposed at the center of the vibration isolation and damping device can isolate and weaken the vibration effect in the horizontal direction, and therefore the vibration effects are simultaneously isolated and weakened both in the horizontal direction and the vertical direction. In addition,the multi-dimensional vibration isolation and damping device with the anti-drawing performance has superior anti-drawing performance, and can effectively bear and consume the drawing force exerted bya building on the vibration isolation and damping device.

Description

Technical field [0001] The invention relates to a multi-dimensional vibration isolation and damping device with pull-out resistance and a vibration isolation and damping method thereof. Background technique [0002] Earthquakes are one of the main natural disasters. They have long posed a huge threat to human life and safety of buildings. Strong earthquakes can cause serious damage to buildings and even collapse. As a superior vibration control technology, vibration isolation and damping technology is effectively used to control seismic effects. [0003] At present, a vibration isolation structure that is more effective for earthquake control is to install a vibration isolation device between the bottom of the structure and the foundation to extend the natural vibration period of the structure and absorb seismic energy, thereby reducing the seismic response of the superstructure. At present, vibration isolation technology is mainly used to isolate horizontal seismic effects. Howe...

AI Technical Summary

Problems solved by technology

However, the traditional multi-dimensional vibration isolating device can play a good role in the process of bearing pressure, but the effect is not good when bearing the action of tension. The drawing performance is poor, which seriously affects the effect of multi-dimensional vibration isolation and vibration isolation on vertical seismic action.
