Abstract

According to the structural properties and basic isolation theory, a new three-dimensional composite isolation pier was developed, which can effectively reduce the horizontal and vertical loads due to earthquake. This study introduced the isolation device configuration, work principle, and design theory. To evaluate the structural performance of the three-dimensional composite isolation pier, shaking table test of the rigid body mass was carried out. The test results show that the composite isolation device exhibites superb isolation performance. Furthermore, the proposed composite isolation device improved the cost-effectiveness and constructability, which can be used for the practical engineering in the Chinese rural area.
