Abstract

The invention discloses a multi-dimensional vibration isolation and damping device with multi-directional anti-drawing and pre-tightening functions 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, steel hinge ropes and a core damping pad, wherein the parts such as the pre-pressing type cylindrical dampers, the steel hinge ropes and the core damping pad are disposed between the upperpressure-bearing steel plate and the lower pressure-bearing steel plate. According to the multi-dimensional vibration isolation and damping device, the pre-pressing type cylindrical dampers connectedwith the pressure-bearing plates through the steel hinge ropes and distributed on the periphery of the vibration isolation and damping device can attenuate the vibration and effect in the vertical, horizontal and torsional directions; and the core damping pad disposed at the center of the vibration isolation and damping device can isolate and attenuate the vibration effect in the horizontal direction, and therefore the vibration effects are simultaneously isolated and attenuated in multiple directions.

Description

technical field

[0001] The invention relates to a multi-dimensional vibration isolation and damping device with multi-directional anti-drawing and pre-tightening force functions and a vibration isolation and damping method thereof. Background technique

[0002] Earthquake is one of the main natural disasters. It has long been a huge threat to the safety of human life and the safety of buildings. Strong earthquakes can cause serious damage to buildings and even collapse. As a superior vibration control technology, vibration isolation technology is effectively applied to the control of earthquake action.

[0003] At present, a more effective control isolation structure for earthquake action is to install an isolation device between the bottom of the structure and the foundation to prolong the self-seismic period of the structure and absorb seismic energy, thereby reducing the seismic response of the upper structure. At present, seismic isolation technology is mainly used to i...
