A Design Method of Tensile Sliding Isolation Bearing

Abstract

The invention provides a tension-resisting sliding shock-insulating support base and a design method thereof. The tension-resisting sliding shock-insulating support base comprises an upper guide rail, a slide block and a lower guide rail in turn from top to bottom; the slide block comprises an upper slide block, a lower slide block and a middle rubber interlayer; the upper slide block is in sliding connection with the upper guide rail; the lower slide block is in sliding connection with the lower guide rail; the upper slide block, the middle rubber interlayer and the lower slide block are connected through a connector; an X directional slide slot is formed in the top of the upper slide block along the length direction thereof; a Y directional slide slot is formed in the bottom of the lower slide block along the length direction thereof; the middle rubber interlayer is connected between the upper slide block and the lower slide block and on the joint position; the thickness of the middle rubber interlayer is 6-12mm. The tension-resisting sliding shock-insulating support base can solve the technical problems of high rigidity of shock-insulating layer, poor damping effect, poor structural vertical tension resistance and low structural anti-dumping capacity of the traditional shock-insulating support base.

Description

technical field [0001] The invention relates to the technical field of shock absorption and isolation, in particular to a design method for a vertically tensile sliding shock-isolation device used in the field of building shock-isolation. Background technique [0002] With the development of seismic isolation technology, it has become a trend to be popularized and applied to high-rise buildings, especially residential buildings, because of its ability to greatly reduce the seismic action of the superstructure and reduce the size of the main structural components. In a seismic isolation structure with a large height-to-width ratio, it is sometimes difficult to achieve the optimal shock absorption effect by using pure rubber isolation bearings; The tensile strength of the seismic bearing itself is very weak, and there are certain potential safety hazards. On the other hand, the existing technology uses ball slide rails, the pressure bearing capacity of the support is limited,...
