DeSoto Bridge Gusset Plate Damage-Minnesota

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Dear Seaint Friends: Here is a story on the Desoto bridge in Minnesota, which last week it was discovered that it had gusset plate "bending" as stated by the MnDOT which closed the bridge to car traffic. I spent Monday and Tuesday here doing a reconnaissance of the damaged bridge and continue my collection of perishable data and analysis of the case in the hope of learning lessons from this damage (fortunately causing no casualties or injuries) to improve bridge engineering and gusset plate design. My initial assessment is that this is gusset plate edge buckling probably caused by excessive force delivered to the gusset plate by the heavier than original design live load and addition of 2" of surface concrete to original 6" deck slab. In a couple of weeks, if we come up with any publication or interim release of information on this I will let you know here.


Best wishes.
