A 16 pile group, consisting of diameter concrete piles, were cast in situ in a clayey soil whose unconfined compressive strength is 1100 psf. Each pile is 60 ft long and the pile spacing is 2.5 times the pile diameter.The water table is at the ground surface and saturated unit weight of the clay is 118 lb/cu.ft. using a factor of safety 3 and a reduction factor =0.45, compute the allowable capacity of the piles acting as individuals
