Calculation Procedure <br /> ll Closed Shapes_ method.The geometric properties for closed shapes are computed by using the Polygon <br /> All closed shapes are represented by closed polygons. t"„urvilineer and circular shapes or <br /> edges are represented by several straight line segments.The properties the overall shape <br /> are computed by geometric summation of the properGea of a trespeeoid defined by <br /> projection of two consecutive points of the cross-section on to the x and y axis: <br /> 2) Open Shapes: <br /> The geometric properties for open(thin wailed)shapes are computed by using the Polyline <br /> method. All open shapes are represented by polyiinea. Curvilinear end circular shapes nr <br /> edges are represented by several straight line segments.The properties the overall shape <br /> are computed by geometric summation of the properties of a line defined by projection of <br /> two consecutive points Of the cross-section on to the x and y axis. <br /> for details refer to Me User's Manual <br /> FOOTING SIZING CALCULATIONS <br /> 1) LOADING <br /> Dead Load= 7 psf <br /> Live Load= 100 psf <br /> Total Load, RAMP_TL= 107 psf <br /> 2) FOOTING ON SOIL <br /> Soil Allowable Bearing Pressure= 1500 psf <br /> 7' Platform Center Column,Area= 12.25 psf <br /> Max Load= 1311 # <br /> Min.
