Active control shock-absorption method

Abstract

The invention provides an active control shock-absorption method. The method comprises the steps that a control device is arranged outside a building to monitor the building; when an earthquake occurs, and the control device exerts outer force to reduce the vibration response of the building. The control device is an active bracing cable system or an active inclined strut system or an active harmonious quality damper. The active control shock-absorption method provided by the invention does not influence the member size, and therefore users have small economic burden.

Description

technical field [0001] The invention relates to an active control damping method. Background technique [0002] When an earthquake occurs, the ground vibration will cause the dynamic response of the engineering building, and the ground seismic energy will be input to the building, so to make the vibration finally stop, it is necessary to dissipate a large amount of seismic energy received by the building. Generally speaking, the strengthening of the building's own seismic performance is to improve the ability of the building's seismic system to resist earthquakes, and the lateral stiffness is increased to protect the building's seismic system, such as strengthening the reinforcement, increasing the cross-sectional size, and improving the material strength. Through this Buildings strengthened by this method can make the damage within a certain allowable range, but this method also has the following disadvantages: because the elastic deformation of the building structure canno...

Generally speaking, the strengthening of the building's own seismic performance is to improve the ability of the building's seismic system to resist earthquakes, and the lateral stiffness is increased to protect the building's seismic system, such as strengthening the reinforcement, increasing the cross-sectional size, and improving the material strength. Through this Buildings strengthened by this method can make the damage within a certain allowable range, but this method also has the following disadvantages: because the elastic deformation of the building structure cannot consume energy, so in order to consume the energy input by the earthquake, the building structure must pay for plastic deformation to consume energy. Especially in the case of a strong earthquake, the building structure will not be able to guarantee its own safety. Due to the suddenness of the earthquake, it is difficult to control the damage of the building structure during the earthquake. In order to meet the basic design conditions, not only will the component size be too large large, but also increase the economic burden
