Lateral Load Capacity and p-Multiplier of Group Piles with Asymmetrical Pile Cap under Seismic Load

Earthquakes are a high-risk natural phenomenon in Indonesia, which is between three tectonic plates: the Eurasian, Pacific, and Indo–Australian plates. This study examines response of bored piles with asymmetrical pile cap Auditorium Building Brawijaya University to seismic loads, still rare conduct this research. assessed based on 3D finite element-numerical approach, where lateral resistance p-multiplier values compared effects combination stiffness, soil stiffness. The behavior deflection group single square gives good agreement. side slope can increase shear zone, resistance, most considerable lowest occurs horizontal direction, opposite loading direction. In addition, configuration that not symmetrical an increasing value followed by from element method was within recommended range.
