The authors have proposed an analytical model to simulate the low cycle fatigue behavior of a degraded pipe against excessive seismic loading. A series of elasto-plastic analyses have been carried out in order to investigate the experimental behaviors of degraded elbows. It has been shown that the ovaling, ratcheting, buckling, and leak behaviors of locally thinned elbows can be simulated well by the proposed method.
