5. Two long boundary walls run parallel to each other at a center to center distance of 1 meter apart. The width and height of the first wall are 0.30 m and 2.5m respectively. While those of the second are respectively 0.18m and 3.5m. Plot the distribution of vertical stress intensity due to walls on a horizontal plane, 1m below ground level. The walls have negligible depth of foundation and are made of brick masonry (y = 19.2 kN/m cu)
