Re: Traffic Railing post loads

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I don't doubt it, but I wonder if it was like the "standard" overpass in Texas, reported in ENR a while back, where a freeway truck hit one concrete column, which precipitated the collapse of the whole overpass.  Standard, or substandard?

It was a D.O.T. standard.

Just a pickup truck, wow!  What if it had been a loaded transit mix truck?  Sounds like a pretty marginally-inadequate design to me.

Don't skimp on the base.  We just had a case where a pickup truck was saved from going off of a bridge by the heavy base anchorage.  As it was, the hooked anchor bolts actually straightened out and almost came completely out of the concrete.
