EVALUATION METHOD ON RESISTANCE OF NODULAR PART FOR NODULAR CAST-IN-PLACE CONCRETE PILE

Abstract

This paper describes the evaluation method on the resistance of a nodular part for nodular cast-in-place concrete pile acting both compressive and tensile loads in sandy ground. The resistance of a nodular part is properly separated into three components, the shear resistance of cylindrical area, Rs , the bearing pressure of circular area, Rtb , and the shear resistance of inclined area due to the increase of horizontal stress, Rts . The validity of the evaluation method were examined by comparing the calculated values and the results of in-situ vertical loading tests.
