A 600mm diameter open ended steel pipe pile is driven to the soil profile mentioned below. Loose silty sand layer has a Ymoist=16.5kN/m3 and Ysat=18kN/m3, medium dense well graded sand layer has Ysat=20kN/m3 . Laboratory tests have shown that effective internal friction angle of silty sand and well graded sand are 30º and 35º respectively. Calculate the toe bearing capacity by using Vesic/Kulhawy method. Using a FS of 3, calculate the allowable downward load capacity of the pile.
