This is the helicorder from a typhoon Tino on Nov. 3rd. You can see the gaps where the power was out. The later gap, during the typhoon, was the delay until the building’s generator started, I switched over to generator power, and it rebooted.
I’m on the 17th floor, and could even feel the building swaying. I couldn’t see anything in any of the other helicorder channels.
Wow! How strong were the winds for this typhoon that you could feel the building shaking?
Hope that everyone is safe where you are, even if I imagine that such a storm has come with its share of damages.
The highest winds were 125MPH, but it didn’t hit us directly.
It was nothing compared to Odette in December 2021 which had 175MPH winds and hit us directly, but that was before I had the RS. The building was really moving a lot during that one, about as much as a 4-5 earthquake, but not as periodic.
We always joke that it was raining air conditioners, because about 25 of them were ripped out and ended up smashed on the pool deck and in the pool and 1 made it out into the street. (They are basically window units but there’s a special opening just for the aircon. Glad I put a few screws in mine to keep them from sliding out.)
Odette was pretty wild, we didn’t have utility power for about 2 months and they only had enough fuel to run the generators about half the time. It took a couple of years for everything to fully recover.
Anyway I have read that the strength requirements for buildings are greater for hurricanes/typhoons than they are for earthquakes. I can imagine a sail the size of our building in a 175MPH wind exerts a lot of force.
That’s wild, but I assume it’s something regular with strong typhoons and hurricanes in areas that are prone to such weather systems.
I had this Calculation of wind load on building side walls - Eurocode 1 in my bookmarks since I don’t know how long ago. It could be useful to see what wind load your building was actually experiencing.
I remember reading a couple of articles regarding the Burj Khalifa wind load calculations, as all the models up until that point were somewhat obsolete given the sheer size of the skyscraper.
