FATIGUE ANALYSIS OF ALUMINIUM BOX-STIFFENER/WEB FRAME CONNECTIONS BY NOMINAL, STRUCTURAL AND NOTCH STRESS RANGE APPROACHES

摘要

The fatigue strength of aluminium box-stiffener/web frame connections is investigated by means of a nominal, structural and notch stress range approach in this study. Three types of joints with different geometry/weld refinement and, hence, costs have been investigated both numerically and experimentally. The results are compared with values interpreted from existing codes.
