Evaluation study of pull-out capacity and deformation of bored pile foundation in a Jakarta building construction project

Abstract

This study uses the finite element method to determine the value of deformation and Pullout Capacity on the Bored Pile. The results compared the calculation of the value of the deformation and Pullout Capacity on the Bored Pile with the finite element method with the pullout test results. The research method used finite element modeling and manual calculations. The results achieved in this study are that Soft Soil & Hard Soil modeling 6.47 mm for deformation and 267.495 tons for Pullout Capacity is closer to the actual value and MC Modelling is 9.08 mm for deformation and 268.497 tons for Pullout Capacity, which is the farthest modeling the actual value with a difference of approximately 50%. This is due to differences in correlation and actual soil type conditions between modeling and field conditions, because the finite element method modeling is assumed to be a perfect pile.
