Shear Ignorance NIST and WTC7

[Ace Acme]

4. Surely you jest

The girder has maybe 35 square inches of bearing surface on its seat.

When it's pushed half way off, it has only 17 square inches of the flange bearing on the seat, but the web is
still bearing on the seat.

When it's pushed 3/4 of the way off, it has only 8 square inches of bearing, and the web is off the seat.

At this point, the overload of the flange on an unstiffened girder will cause the flange to bend upward,
facilitating the push-off.

With the stiffener plates on, you have to push the girder all the way, 100% of the way off the seat, before it
falls off.

Of course with the shear studs on the girder it's not going anywhere anyway, but what's the fun in that.
We're all going to pretend there were no shear studs, aren't we?
