Somthing that disturbed me is when you see the aftermath in Florida. I still think there was some kind of problem with the concrete. That brige looks like a giant box of korn flakes got dumped all over the place. Now is there such a thing as explosive decompression of concrete? Just don't get how that much structure can look like a chrusher did it's job. You can see some pretty large pieces af agri gate in it. Just thinking.

when concrete fails under severe compression it is explosive by nature and happens very suddenly. That is why all the design codes limit the amount of steel for tensile stresses so that failure is by stretching of the steel before the concrete in compression explodes. And you can tell that failure is going to happen by all the cracks in the concrete around the steel reinforcement
