Ugh. Looks like a bomb site

Interestingly there was a Magnitude 3.9 ‘earthquake’ off the coast of Florida in the last week caused by Navy bombing exercises.

It seems like a stretch to relate the two, but could it be ruled out as a cause?

Can someone with local knowledge give an idea of the seismicity of that area and whether a M3.9 earthquake would be significant compared to what it would (should) have been designed for in 1981?

There is a underground parking garage under the portion of the building that collapsed.

Gusmurr, when this building was constructed, Miami did not require seismic design. It would have been designed for significant winds though.

I can’t see the military exercise being the culprit. If I were doing the investigation, I would think corrosion first. We will have to see as it plays out.

Prayers to anyone trapped in the rubble or injured in this.

That's total and complete system collapse. You couldn't get it to pancake like that if you tried to demolish it.

Looks like panel construction - echoes of ronan point maybe?

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Cool_Controls, we’re did you get the information that there is underground parking? With the buildings proximity to the Atlantic, that would be a very complex design and construction.

Wow! And tragic to put it in a single word. My thoughts and prayers are with everyone effected.

Does anyone if this building was concrete or steal framed? Or know any specifics?

"Complete collapse of a part of the building" is a better description than "partial collapse."

My glass has a v/c ratio of 0.5

Maybe the tyranny of Murphy is the penalty for hubris. -

This might be important:

Article said:
Authorities have not yet determined what caused the building to collapse but confirmed that renovations had been underway on the roof

Overloading leading to progressive collapse?

I cannot tell from the photos. Does it look like post tensioned construction or conventional rebar? Is 1981 construction too early for post-tensioning?

Current Google imagery shows construction in the adjacent lot:

[pre][/pre]It looks like a pseudo pan joist system formed with insulation. I am not familiar with that technique. It looks cast-in-place. I cannot tell if the reinforcing is PT or conventional.

Very odd for a 40 year old building to fail in a catastrophic way like that. Be interesting to see what the cause may be.

I can't see a re-roof causing this. From the video it looks like failure initiated at the base. It would take an awful lot of materials to add enough load to a column to fail it.

Being so close to the Atlantic it could be some sort of long term corrosion.

Or something nefarious in the parking garage.
