Description
Technical Field
The invention relates to a friction sliding self-resetting three-dimensional shock insulation and vibration reduction support.
Background
Intense earthquakes are serious natural disasters that currently threaten humans. The structure facing the traditional design relies on plastic deformation of the structure and the components to dissipate energy, and its shock resistance is largely dependent on the ductility level of the structure. At the same time, a large number of seismic records show that the damage to the building caused by the vertical component of the seismic action is not negligible.
With the rapid development of urban construction, the influence of environmental vibrations such as rail transit, high-speed railways, vehicle vibrations, mechanical equipment vibrations and the like on the safety and the use function of a building is not ignored, and the influence gradually becomes a main factor influencing the use of the building.
On the one hand, the vertical rigidity of the traditional vertical vibration reduction support such as a thick meat rubber support, a steel spring (coil spring or belleville spring) vibration isolation support and the like applied to the field of building structures at present is small, so that the vertical rigidity of the structure can be effectively reduced, and the effect of isolating vertical vibration is achieved. However, due to the poor deformation capability of the support in the horizontal direction, when a horizontal earthquake action is encountered, larger horizontal deformation occurs in the horizontal direction (X direction and Y direction), the spring instability or the instability of thick meat rubber is directly caused, the vibration isolation support fails, the vertical bearing capability is lost, and even the upper structure is in danger of overturning. Therefore, the vertical vibration reduction support has small deformation capacity in the horizontal direction, and the effect of isolating the earthquake action in the horizontal direction cannot be realized.
On the other hand, the conventional horizontal shock-insulation supports currently applied to the field of building structures, such as natural rubber supports, lead rubber supports, high-damping rubber supports, elastic sliding plate rubber supports, friction pendulum supports and the like, are generally smaller in rigidity in two horizontal directions (X direction and Y direction), and larger in rigidity in the vertical direction (Z direction), so that the shock-insulation support is mainly deformed in the horizontal direction. By arranging the shock insulation support at a proper position of the structure, the horizontal rigidity of the structure can be reduced, so that the effect of reducing the horizontal earthquake action of the upper structure is achieved; however, the vertical earthquake action and the vertical vibration action of the shock insulation structure cannot be reduced due to the fact that the vertical rigidity of the shock insulation support is high. Therefore, the traditional horizontal vibration isolation support cannot meet the design requirement of engineering structures of vibration double control.
Therefore, it is necessary to design a horizontal and vertical vibration dual-control device to solve the adverse effect of horizontal vibration or vertical vibration on the stability of the main structure, and improve the safety and comfort of the structure.
