Description

Vertical vibration isolation device

technical field

The invention relates to the technical field of building shock isolation, in particular to a vertical shock isolation device.

Background technique

The base isolation technology forms an isolation layer by setting an isolation device between the bottom of the structure and the foundation, prolonging the natural vibration period of the structure to reduce the response of the structure under earthquake action. So far, a large number of buildings using the base isolation technology have withstood the test of the earthquake, which has confirmed the effectiveness of this isolation technology. However, the base isolation technology widely used at present can only effectively isolate the horizontal seismic component, and has almost no isolation effect on vertical earthquakes, and sometimes even amplifies the vertical seismic response. However, a series of strong earthquake records show that there are strong vertical ground motions near the fault, and some vertical acceleration peaks are close to or even much greater than the horizontal acceleration peak. Therefore, effective vertical isolation of buildings in high-intensity areas, especially near fault areas, is particularly important.

In response to the above problems, many scholars at home and abroad have conducted in-depth research on vertical vibration isolation technology. The existing vertical vibration isolation technology is mainly divided into four categories: 1) thick layer rubber; 2) coil spring and disc spring ;3) Air springs; 4) Vertical TMD system. Scholars have developed different types of three-dimensional seismic isolation bearings by combining the above-mentioned types of seismic isolation bearings with conventional laminated rubber bearings in series, in parallel, or placing rubber bearings obliquely. The structure of thick-layer rubber is simple and the force principle is clear, but the bearing capacity is small, and the bearing is prone to vertical instability when the shear deformation is large; The height is large, and problems such as stability and sway need to be solved; the air spring type three-dimensional seismic isolation bearing has the risk of gas leakage; the vertical TMD system can only play an energy-dissipating effect in a fixed seismic frequency range. When the frequency exceeds its design frequency range, the system will increase the vertical seismic response of the structure.

Generally speaking, although the existing vertical seismic isolation devices have their own advantages, they are still rare in engineering practice. At present, there is no reasonable and feasible vertical seismic isolation device for engineering promotion and application. Therefore, there is an urgent need to propose a vertical vibration isolation device that is feasible in terms of device structure, performance, and economic applicability.
