Description

Technical Field

[0001] The utility model relates to the technical field of seismic isolation bearings, in particular to a tensile seismic isolation bearing. Background Art

[0002] The land price in big cities is expensive and the houses are densely packed. In order to give full play to the utilization rate of land per unit area, we can only occupy the sky but not the land, and take the approach of adding more floors. However, under the condition of this ultra-high-width ratio far from the safety factor, it is obviously not possible to ensure the absolute stability of super skyscrapers without adopting new technologies. The taller the building, the greater the lateral thrust of the wind on the building. The wind force on the high-rise part of the skyscraper is several times higher than that on the low-rise part. The impact force of the wind increases geometrically according to the height of the building. For example, the impact force on the top of a 100-story building is 4 times the wind force on the top of a 50-story building. For areas where earthquakes occur frequently, it is very necessary to add seismic isolation design, especially large public buildings such as hospitals, schools, municipal transportation and aviation. However, the existing rubber seismic isolation bearings have low tensile yield strength, which limits their application in buildings with too high a height-to-width ratio or large non-seismic effects such as wind loads.
