1. Consider the uniformly loaded rectangular region shown in the figure. The area carries a uniform pressure distribution, qo, of 150 kPa. Calculate the increase in stress, Ao, at a depth (z) of 20 m below ground surface at each of the following coordinate locations. Complete the table shown for a through c. Create a similar table for solving d. a. The center (0,0) b. The corner (6, 15 ) c. Midpoint on edges (0,15), (6, 0) d. Outside of loaded area (10, 25) 30 m 12 m Coordinates (6 , 15 ) (6, 0) (0, 15) (0, 0) x' y' m=x'/z n=y'/z Influence factor, lo Δσ-formula Δσ Value (kPa) Note: For determining lo, use table provided and interpolate between numbers if necessary, or calculate using the formula for the stress increase under the corner of a uniformly loaded rectangle.
