The Development of an Algorithm to Determine Axial Capacity of Piles from SPT N-Values

An algorithm was developed to determine axial capacity of piles in sand and clay. The standard static formulae to determine pile mcapacity in clay were selected (a-API, A, SEMP and RAND) and the calculated capacities were calibrated using measured results to produce prediction formulae. For capacit...

The standard static formulae to determine pile mcapacity in clay were selected (a-API, A, SEMP and RAND) and the calculated capacities were calibrated using measured results to produce prediction formulae.
