I am a 'Port Engineer' (run/maintenance of boats) not Structural. The design engineer gave us a structural detail on a small pipe pedestal welded to the deck. One of the gusset is showing a Principal stress of 14.027 ksi at the very tip of the gusset (screen print attached). The maximum allowable stress on the specs is 12.8 ksi. The designer said it is ok since the Von Mises is only 12.783 ksi and just the very tip of the gusset is above the 12.8 allowed. Do we need to request thicker plates on the gussets ?
Your expert replies are much appreciated.
