Reaction Force (Again)

Hi all,


I have modelled an offshore support frame and applied an external force and gravity to include the self weight of the frame. (Please note the default mass properties have been overridden to account for missed components). However, when I assess the reaction forces underneath the 15mm doubler plates, the reaction in the Y-axis is greater than the applied load + self weight of the frame.


Below is an image of the doubler plate and reaction forces. These doubler plates will be secured onto the deck of a barge by means of a fillet perimeter weld, hence the fixed restraint in all directions in the static simulation.




Does anyone have an explanation why these forces are greater than the applied loads?
