Eisboch A hit on any piece of unprotected or improperly secured door or window opening on a 200 mph rated structure will indeed impact on the integrity of the structure. Hilarious. JimH, the Ohio idiot, is now an expert on hurricane rated structures. What a laugh. Real Florida natives do not live on the coast, we have better sense. The coast moves around and a 20' surge can ruin things. FL Crackers who needed to be at the coast to fish for mullet would have frame houses with the electrical stuff coming from the ceiling in case of flooding and none of that dry wall either, and insulation, hell, this is FL. They'd furnish it from a rummage sale and when it flooded you'd see all the mattresses being burned and then they'd go to another rummage sale. Now, these fools have homes worth millions of dollars in a place where they are guaranteed to get hit and they expect me o help pay their insurance, morons. AS far as things o see here, Thank God ppl are stupid enough to think Disney or MGM is great cuz it keeps em away from the good stuff. Put razor wire along I-75 and dont let em out of the Miami-Orlando-Atlanta corridor. Tourist, pay yer money and git souvenirs of plastic alligators from China, THEN GO HOME. |

I know that when we decided to add an aluminum framed, screen enclousure on the pool we had beside the Florida house, we ran into a bee's nest of permitting regulations and requirements. In order to have any part of the enclousure attach to any part of the house or deck, we were required to get a professional structural engineer, certified in Florida, to approve it, including modifications required to ensure that the method of construction and attachment met current codes. The criteria was wind speed, and I believe at the time it was 150 mph. This was in addition to having the screen enclousure frame itself to be designed to 150 mph wind. They didn't care about the screening .... in fact it is designed to blow out at a certain wind speed, reducing the sail effect on the aluminum frame. Eisboch |

I believe the terms are "wind load" and "wind load rating." |

Eisboch There was a statewide building code enacted in 2001 I think. In it there were a lot of more stringent specs on windows, doors,shingles,truss tiedowns ect. Pool screens had enhanced specs written too. Countys could make any of those specs more stringent to suit their needs. Most of the hurricane damage you see nowadays is to older homes (pre 2001) and to mobile/manufactured homes . Did your double doors open in as you would normally expect, or did they open outward? Mine open outward and someone said to me that's part of the new codes. I didn't bother to verify that. |

Eisboch While a structure is designed using specific wind data, in Florida's case, the FBC basically the IBC with amendments, and the IBC uses ASCE 7-05 which most building codes use, and those wind maps are based on 100 year data. BUT a structure isn't "rated" by anyone, unless a private entity, say the builder, decides to do so to make a selling point. Here is why. Let's say we have a wind of a certain speed and a certain direction blowing on a rectangular building. Even though the speed is constant (here's where we show Harry and JimH don't know ****~!) the wind PRESSURE is NOT constant. Have you ever seen a mobile home on the side of the highway where part of the siding has blown off when towing? Notice where the siding fails nine out of ten times. The rear corner. Negative pressure from the wind coming around that corner has sucked the siding off! In short, the windward wall has a postive pressure of X amount, the leeward wall has a negative pressure of Y amount, they are hardly ever the same value. Then you have the roof. Slope, wind direction, area, etc. all have an affect on the PRESSURE. In short, we are really designing for this negative and positive pressure as opposed to wind speed. We simply use data in the form of wind speed to mathematically arrive at those pressures. And it goes further, terrain makes a big impact, as well as nearby structure. |

Mine open outward and someone said to me that's part of the new codes. I didn't bother to verify that. That was the problem. If you recall, the main front doors opened inward. All the rest of the double doors (there were two downstairs and one off the master bedroom upstairs) opened outward. The wind blew the front doors open, inward and the whole house then became a whirlwind, blowing the other doors open outward. I think that house was built in 1998 or thereabouts. Anyway, the repairs included a new, double door entry that opened outward. That damage was cause by the first of the three hurricanes that year. Wilma, the last and worst in terms of wind, caused very little damage, mainly because previous damage had been fixed to new code standards. I am still amazed that all those floor to ceiling windows in the main living room held. I still think it was because we had window tinting film on them. Eisboch |
