Self-resetting shock insulation structure system capable of preventing shock insulation layer from being pulled

Abstract

The invention discloses a self-resetting shock insulation structure system capable of preventing a shock insulation layer from being pulled, and belongs to the field of building structure engineeringshock insulation. Vertical pre-stressed cables are arranged in a high-rise structure, and an inclined reinforcing support is arranged on a structure connecting layer, so that the self-resetting shockinsulation structure system with the shock insulation layer not pulled is formed. The high-rise structure is connected with a foundation through a shock insulation support, the vertical pre-stressed cable is arranged in the high-rise structure, the lower end of the vertical pre-stressed cable is anchored to the foundation, the upper end of the vertical pre-stressed cable is connected to the structure, and the inclined reinforcing support is arranged on the structure connecting layer. By adjusting the vertical pre-stress level, it is guaranteed that the shock insulation layer is not subjected to tensile stress, the shock insulation support is not subjected to tensile damage, and therefore the structure shock insulation effect under a large shock effect is guaranteed; and by adjusting the vertical pre-stress level, the height-width ratio of the shock insulation structure system can break through the limitation of a standard range, and the height of the shock insulation structure can be continuously increased compared with the height of a common shock insulation structure.

Description

technical field [0001] The invention relates to a self-resetting shock-isolation structure system for preventing a shock-isolation layer from being pulled, and belongs to the field of structural engineering shock-isolation. Background technique [0002] For many high-rise structures or structures with irregular planes and spaces, seismic isolation technology is often used to reduce their seismic requirements, thereby improving their seismic safety. However, this type of isolation structure is prone to tension on the isolation layer under rare earthquakes. For example, (1) the height-to-width ratio of the isolation structure is relatively large. When the earthquake is large, the horizontal inertial force of the upper structure will be large, making the structure Overturning deformation occurs, so that the isolation layer is tensioned; (2) The isolation structure is irregularly arranged, and there is an obvious eccentric torsion effect during the earthquake, which leads to the...

Problems solved by technology

However, when the height-to-width ratio of a high-rise structure increases, it is still possible to damage the anti-tension device and cause damage to the seismic isolation layer. Therefore, the height-to-width ratio of the structure needs to be limited within a certain range.
