U 777I NC. <br />FORCE DETAILS <br />The details below shown how the forces and moments are calculated for each force component. The values shown <br />are not factored. All loads are based on a unit width (ppf / kNpm). <br />Layer <br />Block Wt <br />I X-Arm <br />Moment <br />Soil Wt <br />X-Arm <br />Moment <br />1 <br />423.04u� <br />1.23 <br />�519.98 <br />0.00 <br />2.46 <br />0.00 <br />2 <br />846.08 <br />1.23 <br />1039.97 <br />0.00 <br />2.46 <br />0.00 <br />3 <br />846.08 <br />1.23 <br />1039.97 <br />Block Weight (Force v) = block: 2115 X-Arm = 1.23 ft <br />Soils Block Weight (Force v) = 0 ppf X-Arm = 0.00 ft <br />Active Earth Pressure Pa = 412 ppf <br />Pa_h (Force H) = Pa cos(batter + b) = 412 x cos( 0.0 + 22.7) = 380 ppf <br />Y-Arm = 1.67 ft <br />Pa_v (Force V) = Pa sin(batter + b ) = 412 x sin( 0.0 + 22.7) = 0 ppf <br />X-Arm = 2.46 ft <br />Live Load Pq = 132 ppf <br />Pq_h (Force H) = Pq cos(batter + b) = 132 x cos( 0.0 + 22.7) = 122 ppf <br />Y-Arm = 2.50 ft <br />Pq_v (Force V) = Pq sin(batter + (5 = 132 x sin( 0.0 + 22.7) = 0 ppf <br />X-Arm = 2.46 ft <br />Passive Earth Pressures <br />Passive earth pressures are used for resistance of the Leveling Pad, but may be extended upward to assist <br />with the resistance of the wall facing for walls that have deep embedments. <br />Passive Earth Pressure: <br />kp = 3.85 <br />Pp = 312.96 ppf <br />UltraWall 4.0.16287.0 Page 6 <br />
