Abstract
Pile foundation is a structural element utilized to transmit structural load into the soil mass. During design processes, many empirical equations used to estimate axial pile capacity, and a pile load test is conducted to validate the design. In Indonesia, it is common to adopt ASTM D 1143/D 1143M-07 for pile testing. Chinese Code JGJ 106-2014 is another viable option, which has gained popularity recently. This study investigated the load-settlement curves obtained using both codes. The analyses were simulated using the Mohr-Coulomb and the Hardening Soil models. The Hardening Soil model yielded more reasonable load-settlement and load-excess pore water pressure curves than the Mohr-Coulomb model. The reason due to the Mohr-Coulomb model unable to capture the non-linear behavior of soil properly. Furthermore, the results showed that ASTM D 1143/D 1143M-07 and JGJ 106-2014 yielded comparable results. Hence, both methods could be substituted each other. [ABSTRACT FROM AUTHOR]
