WIND <br />TSE Engineer�ng <br />LATE(tHL ANALYSIS <br />The analysis on the previous page detetrnines the wind force on the total exposed wind <br />surface of the buildir�g. For post-frame cor.sWction with embedded p�sts, the amount <br />of wind force impos��d on the main force resistlng system equals the roof projected area <br />pius 3/8 of the wall projected area. <br />Calculatians that foilow adjust the total wir.d force to the design force on a <br />post-fram2 building: <br />INPUT: Pr = 7200 Ibs. (non adjusted) <br />P� = 3750 Ibs. (non adjusted) <br />hr= 15 ft. <br />he = 10 ft. <br />ADJUSTED WIND FORCES: <br />Transverse; <br />VT =[(hr - 0.625 he) / hr] (PT) = 4200 Ibs. <br />Longitudinal; <br />V� _ {[0.375 he + C.5(hr-he)] / [he + 0.5(hr - he)j} (P�) _ <br />Controls <br />1875 Ibs. <br />SE!SMIC <br />The seismic force imposed on the main force resisting system of a post-ftame <br />buiiding is based on the seismic weight of the roof plus 3/8 of those walls that are <br />perpendicular to the direction of the seismic force. <br />INPUT: Building Width = 30 ft.
