N2 - Numerical study was conducted by SAP software to investigate behavior of two spun piles embedded in soft soil which were connected to pile cap based on Indonesia design code. Push over analysis were performed using SAP software with two different axial loads; 0.1 and 0.4 of fc.Ag and two different percentages of rebar on concrete infill. To ensure validity of numerical results, model validation was performed against experimental test conducted by other researcher. Horizontal spring was generated by LPILE software to represent soil. The results found that different axial force as 0.1 and 0.4 of fc.Ag affect the occurrence of moment crack of spun piles by 18% and 39%, respectively. Addition of rebar on concrete infill slightly improve moment crack of spun pile. Both parameters do not affect displacement ductility of pile which defines as ratio of maximum displacement to yield displacement.
