A and C, see Fig. 13,are 3.5 and 4.8 respectively. The pressures at A, B, 0, and D werefound as in Art. 6 and are 2.3; 1.3; 2.3, and 1.5 tons per squarefoot respectively. For soft clay a pressure of 2.3 tons per squarefoot is too great, so piles will need to be employed. Assuming thatthe frictional… … 31 Live Load, 1442 x 17 x 125 = 153,000 pounds.
