Abstract

The invention relates to a variable rigidity shock insulation integral intelligent support seat and belongs to the technical field of building structure shock absorption. The variable rigidity shock insulation integral intelligent support seat is characterized by comprising an upper connecting plate (1), a lower connecting plate (4), a magnetic conduction steel plate (2), a magnetorheological elastic body (3), an excitation coil (5), a magnetic conduction iron core (6), a polymer matrix composite permanent magnet material (7), a lead core (8), a conducting wire passage (9), an upper connecting screw bolt hole (10), a lower connecting screw bolt hole (11) and a driving power supply (12), wherein the a magnetorheological elastic body (3) and the magnetic conduction steel plate (2) are in a circular ring shape or a square ring shape, the excitation coil (5) and the magnetic conduction iron core (6) are arranged inside a support seat, and the polymer matrix composite permanent magnet material (7) provides a bias magnetic field for a closed magnetic circuit. The variable rigidity shock insulation integral intelligent support seat has the effects and benefits that the shock insulation and the variable rigidity are integrated, the structure is simple, the anti-interference performance is high, the two-way rigidity regulation can be realized, different horizontal rigidities can be provided for the structure according to different quake waves, and the destroy of earthquake disasters on building structures and bridge structures is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of shock absorption of building structures, and in particular relates to an integrated intelligent support with variable stiffness and shock isolation. Background technique [0002] Among various structural anti-seismic systems, the technology and theory are the most mature and the most widely used is the base isolation technology. Base isolation is to install a seismic isolation device between the building and the upper structure to form a seismic isolation layer, isolate the structure from the foundation, and use the seismic isolation device to isolate or dissipate the seismic energy to avoid or reduce the seismic energy to the upper structure. input, so as to reduce the seismic response and achieve the purpose of shock absorption. The vertical stiffness of the isolation layer is large, while the lateral thrust stiffness is small, and can provide greater damping, so it can significantly reduce the overall...
