摘要：
Fatigue strengths of scallop details in welded structural members were investigated by experiment and FEM analysis. Fatigue strength of this detail based on nominal stress was extremely low because high stress concentration occurred in the gap of scallop. Fatigue strength based on hot spot stress are plotted on narrow band above the JSSC's E class design curve (80 MPa for 2 × 106 Cycles), which shows that fatigue assessment method based on the hot spot stress is valid for estimating fatigue strength of scallop details.
