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" x 0_044" Hollow Extrusion <br />2) All post sizes listed below the 2" x 3" x 0.044" Hollow Section <br />Note: <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 />aYI. ENa#EER . OEVa.OAEHT CON3U. TANr <br />P.O.
