Experimental study on dynamic behavior of multiply supported piping systems in industrial plants is described. Nonlinear characteristics such as gap and friction appearing between the piping itself and supports is specifically investigated. The response reduction effect due to these nonlinearities is evaluated by the shaking test with a piping-support structural model. From the study, it is shown that the amount of response reduction can be represented by a "response reduction factor" and that the reduction characteristics are examined with the aid of equivalent linearization.
