The truss straps

The truss straps should have been covered with concrete.



Can anyone explain why the truss straps would still be hanging from the walls where the lobby ceiling trusses were attached? Notice how they are also hanging from the level which should have been the ceiling to the first mechanical floor:



When zooming in to the lobby ceiling material it can be seen that no concrete was poured, which can also be said of the floors above it.




For the mechanical floors there were open air walkways, hence the cladding wrapping all around the columns at that level.



So what can explain the truss straps still being there when the trusses they were attached to are nowhere to be seen?

Also notice how above the first mechanical level there is no sign of any floor material on the spandrels - no truss straps, nothing, not even any interior finishes are visible all the way down to the lobby floor. Had there been real floors installed at the time of destruction there should be some evidence of them just as there is evidence of lobby ceiling material.
