For post-frame construction with embedded posts, the amount <br />of wir�d force imposed on the main fomhs resisting system equals the roof projected area <br />plus 318 of the wall projected area. <br />Calculations that follow adjust the total wind force to the design force on a <br />post-frame building: <br />INPUT: PT = <br />P� _ <br />hr = <br />he = <br />3050 Ibs. (non adjusted) <br />1820 Ibs.
