Abstract
Vibration tests were performed to validate two proposed methods of estimating vibration-induced stress, respectively. One was for simple small-bore piping and the other was for complex one. The tests were performed using sine wave or random wave or the field response wave measured on-site. As the former results, the calculated stress using first proposal method showed better agreement with the measured stress than using traditional one. As the latter results, the estimated stress using the second proposal method became to be from 0.5 to 2 times to the measured one.
