Even with the change in projected track they are forecasting winds over 100 mph in Miami for over 14 hours.

The storm is going west of Miami...what if it destroys Homestead? o_o

Saw some pictures of AA counters at MIA before they closed up shop tonight. They had blue tarped all the check in desks. They don’t seem optimistic.

Oppo architects and structural engineers especially:

When buildings are rated for this type of wind, does duration have an impact? Are wind ratings for gusts, or sustained? I’ve seen a couple weaker hurricanes and a number of tropical storms, but the idea of 14 hours of 100mph wind, not to mention the associated debris, is kinda scary.

This doesn’t fully answer the question, but it is interesting.

These buildings should be fine with upgraded building codes, but the duration is going to push a limit i would not be comfortable with. They’ll definitly be a shit load of inspections afterwards.

The bigger concern many have had are the giant cranes that can’t be removed from those under construction.

(not a architect or structural engineer but I did stay at a Holiday Inn Express once)

There are two kinds of structure failures, static failure and fatigue failure. You can imagine it is pretty hard to just pull apart a paper clip by pulling real hard, verses bending it back and forth until it snaps. The first is static the second is fatigue. One big gust blowing apart a building would be static, the building bending back and forth and then failing would be fatigue. Different materials have different properties for fatigue failure and I expect a building to be very different then a paper clip. But none-the-less 12 or 24 hours of high winds would undoubtedly bend and wear out some materials or fasteners so I’m sure the structures would fail at a lower wind speed over a long period of time than they could stand under one big gust.

That’s a good point as well. I remember a high-rise crane getting picked off a roof in NYC a couple years ago by a 70mph gust, if memory serves correct.
