Ft. <br />For a 10'.11" post and 120 m.p.h. wind load or 23 # / Sq. Ft. 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 />an. BGN!!II!R - DE1IB..Of'II!Nr 0(ItMU. TANr <br />P.O.
