Condo 804 Sea Winds Condominiums, 10044 S. Ocean Dr,Hutchinson Island,Fl 34952
Dear Mr. Laprade:
Please know a wind load analysis was completed for the above window replacement, mullion installation and
mullion fasteners as described below.
The analysis included calculating the applied wind loads for the window replacement based on ASCE7-10 with
(1) single hung window of 36"x48; (2) single hung windows of 36"x48"with(1)middle mullion sized at 1"x
2":0.375"; plus (1)108"x80",Exposure D, Wind speed 170 mph,Enclosed Structure, Category II, with Wind
Zone 4, and building height of 106'.
When taking into account the external and internal pressure coefficients and adjustments per the ASCE7-10,the
resulting and governing and most severe applied wind pressure comes to+68.9 psf/-73.5 psf which is less than
the allowable NOA pressures and therefore acceptable to this office.
The applied wind load on the Mullions is 445 lbs on each end. This is below the allowable wind load transfer
from the window to the mullion when fastened to the mullion per the respective NOA 14-1105.01, Table 2A&
2B of 1,5601bs with(4) 1/4"x2.5"tapcons,with min. 2.5"edge distance each end.
To meet the satisfaction of this office and Florida Building Code, please ensure the single hung impact rated
windows and the sliding glass doors are installed per the window manufacturer's direction and as stated in their
respective NOA's (15-0519.08 and 15-0106.08).
