Description
Technical Field
The invention relates to the field of shock insulation/vibration devices, in particular to a high-efficiency energy-consumption tensile self-resetting support.
Background
China is at the intersection of two earthquake zones, so that the earthquake in China is frequent, and the earthquake has the characteristics of high earthquake intensity and high destructiveness. The passive shock insulation and absorption control technology of the structure starts in the 70 th 20 th century, gets the attention of broad scholars due to the excellent control on the earthquake response of the structure, develops the extensive research and is widely applied to the actual engineering.
The traditional view is that horizontal seismic force plays a decisive role in structural damage, so that most of previous researches are focused on the aspect of horizontal seismic isolation technology, the technology is mature, and the application is wide. However, in a high-intensity area, particularly near an earthquake fault or an earthquake center, a vertical earthquake component is large, and the damage effect on a building cannot be ignored. Meanwhile, with the development of urban rail transit, especially when the rail is close to a building, the train runs to cause the vibration of the building structure, and the influence is caused on the safety of the building and the living comfort of people. The operation of machines near buildings or the operation of machine equipment inside buildings can cause the vibration of the buildings to exceed the standard, and the safety of the structure and the comfort of people are influenced. Therefore, the research of vertical seismic isolation/vibration technology is more and more urgent.
The research and development of vertical vibration isolation/vibration technology are mostly carried out along with the research and development of vibration isolation/vibration supports. Most of the vertical shock insulation supports proposed at present are thick-meat type laminated rubber supports or steel spring supports, and the tensile capability is poor. When the upper structure/device of the support is subjected to a larger vertical earthquake action or swings or even topples under a larger horizontal earthquake action, the support can enter a pulled state, the thick-flesh rubber support can be broken and damaged, the steel spring support can be lifted out and failed, and the swing and toppling effect of the upper structure/device of the support is poorly controlled.
