Seismic Responses of Aqueducts Using a New Type of Self-Centering Seismic Isolation Bearing

An aqueduct is a bridge-like structure that supports canal passing over river or low ground, and it an important part of water conveyance system. Aqueduct piers are extremely vulnerable to damage during strong earthquakes can result in structural collapse. Further, excessive seismic displacement will also fracture aqueduct’s rubber water-stop interrupt the normal service after earthquake. Therefore, improving capacity post-earthquake resilience aqueducts great importance. In this paper, new type self-centering isolation bearing, inclined plane guide bearing (IPGB), proposed for design aqueducts, studied both experimentally numerically. Firstly, typical project setting IPGBs introduced. Then, test design, cases, results shaking table tests two different pier-height presented. The responses models studied, show used has smaller better resilience. Finally, numerical simulation method applicable using proposed, its accuracy verified by comparing test.
