Ft <br />For a 10'-11" post and 120 m.p.h. wind load or 23 # / Sq. Fl post choices are: <br />1) 2" x 3" Snap Section - <br />2) All post sizes listed below the 2" x 3" Snap Section <br /> <br />Where job conditions dictate a post height of 10' In a 120 MPH wind zone, a 3" x 3" Roll Formed <br />COULD NOT BE used because when It Is more than 10' tall It can only support 39 SF of roof. On the <br />other hand, a 3" x 3" Fluted Post with a post height of 10'-7" can support an area of 128 square feet of <br />area. Thus, design must satisfy both height and area requirements. <br /> <br />Lawrence.E. Bennett, P.E. <br />aw. ..... ..~ CCMLt.tNlr <br />P.o. BOX ... 80UTH DAYTONA, Ft. 8ttt1 <br />'I1!l..I!PtDI!
