Directing at seismic bracings used in piping systems, this paper firstly introduces the classification, construction and design steps of seismic bracings. The seismic code requirements for design method and load performance testing of seismic bracings are mentioned. Relevant seismic research of bracings is also reviewed. The shaking table test of seismic bracings in a 6-meter full-size piping system was conducted and responses of both floor and pipes were measured on the longitudinal and lateral directions under the table input levels. In addition with theoretical analysis and specification comparison, the seismic performance of bracings and the acceleration amplification coefficient of pipes are studied. The test results indicate that the seismic performance of bracings is good enough to satisfy the seismic code requirement. But the problem of bolt looseness occured in connection parts may further cause the rotation or shift of bracings under continued earthquakes or aftershocks. Based on the results, both technical improvement measures to enhance weak connections and design optimization suggestions considering cost need to be put forwarded.
