Mechanical Performance Tests of a Novel Three-dimensional Isolation Bearing

基于铅芯橡胶隔震垫、组合碟形弹簧和钢板阻尼器的各自力学性能特点,设计开发出一种新型的三维隔震装置,首先简要介绍了该三维隔震装置的组成构造和力学性能设计方法;通过一足尺三维隔震装置分别进行了水平向和竖向力学性能试验。试验结果表明,该三维隔震装置具有构造合理、传力机制明确等优点,在水平向和竖向都能够具有适宜的隔震刚度和阻尼耗能性能,并且在较大水平剪切变形时仍具有良好的整体稳定性。

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.
