Description
Technical Field
The invention belongs to the technical field of seismic mitigation and isolation of buildings, and particularly relates to a tensile friction pendulum seismic isolation support convenient to reset.
Background
At present, the earthquake-proof design specifications of various countries all use 'big earthquake cannot fall down, medium earthquake can be repaired, and small earthquake cannot be damaged' as an earthquake-proof design principle, and the main targets are to protect the structure from being damaged and protect the life safety. The traditional earthquake-resistant structure resists earthquake by enhancing the structural strength, allows structural members to enter an inelastic state during earthquake, has certain ductility, consumes earthquake energy at the cost of damage of the structure and reduces earthquake reaction. From the earthquake damage loss of more than 10 years, all houses designed and built according to earthquake-proof specifications can basically ensure that the houses cannot collapse when rare earthquakes occur. However, the house built according to the traditional earthquake-resistant mode often causes overlarge size of building components in a high-intensity area, and influences the actual use space and the building function; on the other hand, when an earthquake with intensity higher than the fortification intensity occurs, the house can be collapsed after being accumulated to a certain degree due to the continuous damage of the bearing components in the earthquake, and the safety of the house in the extremely rare earthquake cannot be ensured; in many cases, even if the house is not collapsed, the house is difficult to repair because the load bearing members are damaged heavily.
In order to ensure the safety of buildings more effectively, domestic and foreign scholars put forward a building shock insulation technology through a great deal of research. The building shock insulation technology is that a shock insulation layer composed of shock insulation supports (rubber shock insulation supports, sliding supports, friction pendulum sliding supports), damping devices and the like is arranged between a building foundation or a lower part and an upper structure, so that the earthquake energy is isolated and transmitted to the upper structure, the earthquake energy input to the upper structure is reduced, the self-vibration period of the upper structure is prolonged, the earthquake reaction of the upper structure is reduced, the expected earthquake-proof and shock-proof requirements are met, and the safety of a building is ensured more reliably.
The friction pendulum vibration isolation support is not only a pendulum vibration isolation support in nature, but also a sliding friction support, realizes the vibration reduction and isolation function of the support by utilizing the friction between the friction surfaces of the upper base plate and the lower base plate and the spherical crown plate, and simultaneously prolongs the self-vibration period of the upper structure by depending on a pendulum mechanism so as to achieve the effect of reducing the seismic force. Meanwhile, the friction pendulum seismic isolation support has a small structure volume, so that the friction pendulum seismic isolation support is rapidly and widely used all over the world. When the earthquake action is small, the stability of the upper structure can be ensured by the static friction force in the friction pendulum seismic isolation support; and under the great earthquake action, the upper and lower base plates of the support can slide on the contact surface (curved surface), so that the earthquake energy transmitted to the upper structure on the ground is greatly reduced, and the effect of lightening earthquake disasters is achieved.
There is not the tensile measure between the last bedplate of friction pendulum formula shock insulation support for building, therefore friction pendulum shock insulation support generally does not have the tensile function of pulling out, and the support can not restrict the displacement of building on vertical side, can only the pressurized, is difficult to accomplish to draw and presses and compromises, and the some friction pendulum formula shock insulation support has set up tensile structure, but in rare chance earthquake, tensile structure very easily destroys the body structure of friction pendulum formula shock insulation support, influences follow-up support and resets.
