Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of shock isolation building structures. BACKGROUND

[0002] With the development of construction industry, the scale and quantity of building are expanding, and the safety of building is increasingly needed. In addition, many large earthquakes have caused great damage to buildings. Therefore, building isolation and shock absorption have gradually attracted widespread attention, and have also posed great challenges to the design requirements of building isolation and shock absorption in the construction industry. Therefore, building enterprises need to improve and optimize the isolation and shock absorption structure of building, and innovate the application measures of building isolation and shock absorption, so as to enhance the comprehensive performance of building isolation and shock absorption, improve the ability of building to resist earthquakes, and protect the safety of people's life and property. Important public buildings and lifeline projects such as hospitals, schools, museums and nuclear power plants need to recover quickly after an earthquake to provide support for rescue and post-disaster reconstruction. Isolation technology can effectively protect the structure and internal facilities of these buildings, ensuring their safety and reliability in earthquakes. Isolation technology sets an isolation layer between the foundation and the upper structure of a building, which can extend the natural period of the structure and avoid the predominant period of the earthquake, thereby reducing the transmission of seismic energy to the upper structure. Isolation bearings are set in the isolation layer to provide flexible support, allowing the building to slide horizontally relative to the ground under the action of an earthquake.

[0003] In existing isolation buildings, an isolation layer is usually set at the bottom of the frame building structure, and isolation bearings are set in the isolation layer. The isolation bearings can extend the natural period of the structure, avoid the main frequency band of the seismic wave, avoid co-seismic with the seismic wave, and reduce the seismic response. However, the existing isolation system needs to bear the entire building, which requires high load capacity, resulting in reduced service life of the isolation bearings and shortened safety life of the building.
