Steel pipe piles are to be used as friction piles (i.e., pile capacity is from shaft resistance only) in an area where a deep deposit of normally consolidated clay exists. The soil unit weight is 17kN/m3, with shear strength cohesion cu equal to 45 kPa. Using the total stress α-method, determine the design axial capacity due to shaft resistance for a pile diameter of 0.30 m and an embedded length of 10 m. Apply a factor of safety of 2.75.
