Cassie told him that the building was shaking and the pool deck had collapsed.
DB27 said:It's also interesting that many of the columns remain, but I don't see evidence that K/14.1 is still standing. If the beam at the slab drop (K/12.1 to K/16) failed at mid-span due to the missing beam, it would create a sudden eccentric load to column K/14.1, possibly causing it's collapse.
Keith_1 said:I totally apologize but I really don't see any "mechanical roof anchors". To me the term infers a mechanical connection between the base-ply and the underlying substrate, and not the connection for A/C stands, flashings or caps. The term mechanically fastened roof makes me think of anchors on a foam or thin lightweight concrete over a metal deck and not a pored a RC deck.

This caused the pool deck to fail either by hitting a column in the parking area as the ENR article suggests or by overloading the slab.

Keith_1 said:There are absolutely no OSHA deck anchors in this structure. I don't know what scares me the most is that you have absolutely no clue when such things are employed, or how they are employed.
This is a simple midrise, there are absolutely no geometric point that OSHA would require an anchor point for a complex geometry, nor is it tall enough to require a secondary anchorage.
