Hernando DeSoto bridge question

Rate this topic

193 posts in this topic

We must have a structural or mechanical engineer or two, on this Forum.

 

The bridge is closed for inspection and repair, at least six or eight weeks. The inspections are ongoing. What are the odds that the inspectors find more damage than just the one failed four-plate beam? I'd say that they're pretty good, and that there's a substantial chance that the whole damn structure will be declared so damn dangerous as to need replacement. 

 

What do the professionals say?

I'd say the chances of finding more failures are slim.

 

If the other main load bearing beams were damaged the entire bridge probably would have come down when the one failed and the others had to pick up the additional weight bearing. 

 

Where's CnR, he's an engineer.

When he's not being a dick he can be insightful on stuff like this.

Of course there's always the possibility that they will "find" issues so that they can acquire a contract for the repairs. Kind of like finding fault because they need to. Not saying this is the case, but I'm sure that some unscrupulous characters have "fudged" the inspection results in order to obtain a repair/replace contract.

It goes without saying that my commentary is pure speculation and conjecture and should be taken with a grain of salt...

Saw the picture of the crack.....the steel does not look rusty at all..

Major problems.....where the crack occurred prob was being over overloaded by faults in in the design. You have to look at how old the bridge is, METAL FATIGUE..etc etc etc

The symmetry of the crack bothers me...perfectly perpendicular.....uhmn uhmn.

 

Anyway, i am retired, could care less. Let it hit the river bottom and build a new one.....jobs.

Fisher tim do a search using that name and you will find a picture of it.

It is not just a crack, one side is lower than the other...bad news....

Overloading of a specific point or member cause of the design, load and or a fault landru.

I seems to me that that  point was being overloaded....you know with fat people like you crossing at the same time.

Not easy fixing that area.....

BTW, Roman arch design....old as the hills....not too good dealing with vibration in my opinion.

:howdy:

I am NOT an EXPERT even if i play one here.

In my opinion, that bridge will be closed for weeks if not months.

BTW,  duct tape will not work in this situation.
