Description
Technical Field
The invention relates to the technical field of seismic isolation and reduction of buildings and bridges, in particular to a friction pendulum support with a horizontal rotation function for buildings.
Background
The friction pendulum type vibration isolation support is developed by American Earthquake Protection System (EPS) company in 1985, and is firstly used on building construction structures. The nature of the friction pendulum type shock insulation support is also a friction damping support, but the normal function of the support is realized by the friction of two curved surfaces. When the building upper and lower structures are displaced relatively, the swinging member moves like a pendulum. The horizontal motion generates a vertical lifting of gravity, if the friction force is ignored, the motion equation of the system is similar to pendulum motion with equal mass, and the pendulum length is the curvature radius of a spherical surface. By changing the curvature radius of the spherical surface of the support, the swing period of the support can be changed, and the expected shock insulation period is achieved. The kinetic energy is converted into potential energy to consume seismic energy through the vertical lifting of the gravity when the support horizontally moves. The support has certain resetting capability under the action of gravity after an earthquake. At present, a great deal of friction pendulum type shock insulation supports are applied to house structures and bridge engineering.
The friction pendulum type shock insulation support used at present has two kinds of sphere and cylinder, and the better but processing of sphere support performance is difficult, the cost is higher, and displacement restraint is exerted alone to the axial needs when ordinary cylinder support rotates to the direction is single, can not satisfy the antidetonation demand in other directions. When a plurality of cylindrical supports need to be arranged under a structure (a plurality of cylindrical supports are arranged on the same pier), the coaxiality of the cylindrical supports on the same row must be considered, and if construction installation errors cause that the cylindrical supports in a row are not on the same axis or included angles exist among axes of the plurality of supports, excessive abrasion of the abrasion-resistant plate must be caused.

When a plurality of cylindrical supports need to be arranged under a structure (a plurality of cylindrical supports are arranged on the same pier), the coaxiality of the cylindrical supports on the same row must be considered, and if construction installation errors cause that the cylindrical supports in a row are not on the same axis or included angles exist among the axes of the plurality of supports, the defect of excessive abrasion of the wear-resisting plate must be caused, so that the friction pendulum support with the horizontal rotation function for the building is provided.
