Seismic Safety Capacity of a Piping System With Pipe Supports Based on the Shake Table Test Available to Purchase

It is well known that the seismic safety capacity of a piping system itself is considerably high compared to the design limitation from the various preceding studies. But most of the preceding studies focused on the seismic capacity of a piping system without other elements as supports, and the safety capacity may be reduced if the failure at supports, nozzles, or flange connections were precedent to the failure at the body of pipe. Therefore the shake table test on the piping system model with supports was conducted. The piping system model used in the shake table test had three supports, a tank, a valve, and flange connections. Excitations were conducted at several input acceleration intensity, and the response characteristics and the failure mode of the piping system were obtained. The failure mode of the piping system model was the broken damage at a pipe support, and after that the leakage at a flange connection occurred. Though the piping system was damaged at pipe supports, it was shown that the piping system model had a certain seismic capacity compared to the design limitation.
