The invention provides a composite three-way intelligent shock-isolation bearing, which is suitable for building construction, bridges, bases of important cultural relics and other different shock-isolation systems. The upper part of the six shape memory alloys is connected to the prismatic steel top plate through the fixed sleeve, and the lower part is connected to the prismatic steel bottom plate sprayed with damping materials. At the same time, the six disc springs on the prismatic steel bottom plate and the intelligent friction plate jointly support the prismatic steel top plate. When the bearing is subjected to a horizontal earthquake, the upper and lower steel plates move horizontally relative to each other, and the shape memory alloy provides a large restoring force, and drives the friction disc to change the anchoring force of the bolt through the electric deformation of the piezoelectric driver, and exerts intelligent adjustment of the horizontal friction Energy dissipation; when the support is subjected to a vertical earthquake, the disc spring bears the load and deforms, and stores a certain potential energy to consume the vertical earthquake force. The composite three-way intelligent shock-isolation bearing of the invention can effectively solve the three-way shock-isolation problem of structures, and provide guarantee for the safety of building structures and the protection of important cultural relics.
