Home My WebLink AboutSPECIFICATION & DESIGNra L GIRTS: TION NOTES AND DESIGI, POLY ROOF CARPORT THIS CARPORT STRUCTURE MEETS THE FLORIDA BUILDING CODE FOR A HEIGHT 7'-11", EXP. 'C', 150 MPH WIND SPEED. THE TABLES BELOW ARE BASED ON SIMULTANEOUS LOADING AS DEFINED IN THE FLORIDA BUILDING CODE (FBC), CHAPTERS 16 AND 20, AND OTHER REFERENCES SUCH AS ALUMINUM ASSOCIATION OF FLORIDA (AAF) "GUIDELINES TO ALUMINUM CONSTRUCTION IN HIGH WIND AREAS". STRUCTURAL VALUES FOR EXTRUDED ALLOY 6005T5 ARE TAKEN FROM THE ALUMINUM DESIGN MANUAL. 2015 EDITION.

LUCIE. THE CARPORT HAS SOME OPEN AREAS AROUND IT. THE ENCLOSURE IS VERY CLOSE TO THE SAVANNAS PRESERVE STATE PARK. PER THE EXPOSURE CATEGORIES LISTED IN SECTION 1609.4.3 OF THE FLORIDA BUILDING CODE THIS ENCLOSURE SHALL CONSERVATIVELY BE CALLED AN EXPOSURE 'C'. ACCORDING TO THE COMPUTER PROGRAM "WINDSPEED BY LOCATION", A PRODUCT OF 'APPLIED TECHNOLOGY COUNCIL' THE DESIGN WIND LOAD REQUIREMENTS FOR A RISK CATEGORY I ENCLOSURE IN THIS LOCATION IS DICTATED BY A WIND SPEED OF 148 MPH. HENCE, THE DESIGN PARAMETERS BEING USED HERE ARE 150 MPH WIND LOAD, EXPOSURE 'C', RISK CATEGORY I. THE NEW POLY ROOF CARPORT IS BEING INSTALLED BECAUSE THE EXISTING CARPORT, WHICH WAS BUILT IN THE 1990S, WAS DAMAGED DURING A RECENT HURRICANE. THE FRONT IS 7'41" HIGH AND THE REAR IS 8'-5" HIGH; WITH A RUN OF 12.25 FEET GIVES A SLOPE OF ABOUT 0.49 INCHES PER FOOT. THE POLY ROOF CARPORT IS BEING BUILT ON AN EXISTING NOMINAL 4" SLAB THAT IS IN GOOD CONDITION. THIS FOUNDATION IS ACCEPTABLE FOR THIS SCREEN ENCLOSURE. THE DESIGN DRAWING IS SHOWN ON SHEET 2. THE POLY ROOF CONNECTION DRAWINGS ARE SHOWN ON SHEETS 3. - — THE HOST STRUCTURE IS A MODULAR HOME SO 4TH WALL CONSTRUCTION FOR COMPOSITE ROOFS WILL BE USED. THEREFORE, THE COLUMNS, BRACING AND CONNECTIONS SHOWN ON SHEET 2 ARE THE SAME IN THE BACK AS IN THE FRONT EXCEPT THAT THE BACK IS 9 INCHES HIGHER. THERE SHALL BE NO STRUCTURAL ATTACHMENT BETWEEN THE POLY ROOF CARPORT AND THE MOBILE HOME BUT IT IS ACCEPTABLE TO INSTALL FLASHING TO KEEP THE RAIN OUT. THE CARRIER BEAM TO COLUMN CONNECTION CAN BE MADE WITH 7" LONG CHANNELS AND FOURTEEN (14) #12 SMS, SEVEN (7) BETWEEN EACH CHANNEL AND COLUMN AND SEVEN (7) BETWEEN EACH CHANNEL AND CARRIER BEAM, SIMILAR TO KNEE BRACE CONNECTIONS ON SHEET 2. ALSO, SEE OPTIONAL CONNECTION DRAWINGS BETWEEN COLUMNS AND CARRIER BEAMS BELOW.
