【 摘 要 】

In this study, seismic simulation tests were conducted on a stainless steel pipe with fixed groove joints for fire protection systems using cyclic loading. When a seismic load occurred, the deformation of the specimen and the response by the relative displacement between the elements were analyzed. To examine the behavior of the tee joints and elbow (vulnerable elements of the specimen) in the range higher than the ±1° minimum deformation angle in the event of an earthquake, the deformation angle was measured using an image processing method. The von Mises stress was also measured at the tee joint and elbow using a 3-axis strain gauge, and the result was compared with the allowable stress criterion to confirm the seismic performance.
