Abstract

Construction tower own characteristics tall and slender structure making it very vulnerable to lateral loads such as wind and earthquakes that can cause force lift on the foundation on the ground clay consequence pullout force. Analysis capacity Power support pull foundation need reviewed with comprehensive for security construction. Analysis done on the tower 32 m high and with foundation next pile drilling done evaluation to Power support uplift and deformation. Analysis methods using CPT field data, analysis​ reaction placement based on function tower using ETABS software. The uplift capacity was analyzed using a empirical method, while the foundation response was evaluated numerically using Plaxis 2D. The empirical analysis yielded an uplift resistance of 2542.515 kN for the foundation system. The reported safety factor of 5 requires verification based on the calculated ultimate uplift capacity and the applied uplift load. The Plaixs 2D simulation indicated a downward displacement of 200.6 mm under compressive load and an upward displacement of 136.6 mm under uplift load. In the simulation seen foundations that experience loading pressure of 341.1 kN per-pile at condition compressed and reduced to 191.1 kN consequence occurrence pull out, in simulation produce mark factor more factor of safety​ low which is 3.73. This result show that behavior foundation pole drill in the ground clay with analysis empirical and numerical give difference around 77%.
