Experimental Study on Flexible Pipelines Used in Base Isolation Layer
Abstract eng: The flexible pipeline connection is one of the key components for the water supply and drainage system in a base-isolated building. It is able to accommodate the large displacement between the superstructure and the ground. Its seismic performance is extensively examined in this study by a series of tests. Three types of seals, namely rubber-based seals, metal-based seals and asbestine-based seals, and three types of connections, union joints, ferrule fitting connections, and grab-type joints, are examined. The specimens were tested cyclically with the pipes filled with pressurized water, ranging from 1.0MPa to 2.5MPa. It is observed from the test results that the asbestine-based seal leaks earlier than the other two types of seals, and the union joint is not easy to realize the complete boundary of infilled liquids.
