The steel member is a fillet welded built-up section that comprises two flange plates (100mm x 20mm) and a web plate (250mm x 10mm) as depicted in Section A-A. The leg size of the weld is 8 mm. Use an appropriate consequence class. Based on the damage tolerant method and the modified Goodman equation. Determine an equivalent completely reversed stress. Ignore the vibration and dynamic amplification. Use Euro-code 1993-1-9. (a) Calculate the maximum and minimum stresses at steel member section A-A. (b) Check the fatigue resistance of the steel member at Section A-A using the fatigue limit. (c) Discuss the possible failure mode of the steel member due to fatigue loading. State your design assumptions, if any.
