Mechanical Performance Tests of a Novel Three-dimensional Isolation Bearing

A novel three-dimensional isolation bearing(3DIB) was proposed,based on respective mechanical characteristic of lead rubber bearing,combined disc springs and rhombic steel plated damper.Firstly,the configuration department and mechanical design methodology was introduced;the horizontal and vertical stiffness and energy dissipation performance test was performed on a full scale three-dimensional isolation bearing,respectively.The results indicated that the proposed three-dimensional isolation bearing has reasonable configuration and explicit mechanical transmission mechanism;appropriate stiffness and energy dissipation performance can be achieved by reasonable design,keeping favorable holistic stability at plentiful horizontal shear displacement.
