Drilled pile foundations that have been set in hard soil are generally used for buildings with shear walls. By nature, a drilled pile foundation can withstand moments because of the drilled pile’s dimensions and the amount of reinforcement installed. This study presents a structural analysis of a 10-story building supported by a dual system structure to meet earthquake requirements. The results show that, by using a dual system, the earthquake requirements (natural period, modal, story shear, story drift, and P-Delta) are met. Other results show that the base shear force of the shear wall has a value of 58.76% for the X-direction and 63.72% for the Y-direction. The base shear force value of the frame is 41.23% for the X-direction and 36.27% for the Y-direction. Therefore, the requirements of the dual system are met because the resisted base shear force of the frame is higher than 25%. The dual system provides a normal force value of 24.32% for the shear wall, while the frame carries 75.67%. The bearing capacity of the drilled pile with a safety factor = 2.5 is 162 tons for a diameter of 50 cm, 214 tons for a diameter of 60 cm, 340 tons for a diameter of 80 cm, 493 tons for a diameter of 100 cm, 672 tons for a diameter of 120 cm, and 993 tons for a diameter of 150 cm. The result of the pile driving analyzer test values for a 120 cm diameter range from 988 to 1,232 tons.
