High-rise buildings with dual seismic resistance systems require careful foundation design due to significant load variations under different seismic conditions. High-rise buildings with dual seismic resistance systems require careful foundation design due to significant load variations under different seismic conditions. Three shear wall configurations (SW1, SW2, SW3) were analyzed using ETABS software following SNI 1726:2019 and ACI 318-19 standards. Load combinations included dead load (DL), superimposed dead load (SDL), live load (LL), roof live load (LR), and earthquake loads (EQ-X/Y). Compressive forces under DBE loads increased 1.00–1.57 times compared to gravity loads, while MCE loads produced 0.83–1.31 times gravity load ratios. Tensile forces under seismic conditions reached 0.18–0.57 times the compressive forces. Shear forces showed the most significant amplification, with DBE loads producing 3.8–5.5 times gravity load values and MCE loads yielding 2.25–4.5 times gravity loads. The analysis reveals critical design implications for bored pile foundations in seismic zones, particularly the dominance of shear force amplification under earthquake loading, providing essential data for optimizing foundation design in high-rise structures.

High-rise buildings with dual seismic resistance systems require careful foundation design due to significant load variations under different seismic conditions. Three shear wall configurations (SW1, SW2, SW3) were analyzed using ETABS software following SNI 1726:2019 and ACI 318-19 standards. Load combinations included dead load (DL), superimposed dead load (SDL), live load (LL), roof live load (LR), and earthquake loads (EQ-X/Y). Compressive forces under DBE loads increased 1.00–1.57 times compared to gravity loads, while MCE loads produced 0.83–1.31 times gravity load ratios. Tensile forces under seismic conditions reached 0.18–0.57 times the compressive forces. Shear forces showed the most significant amplification, with DBE loads producing 3.8–5.5 times gravity load values and MCE loads yielding 2.25–4.5 times gravity loads. The analysis reveals critical design implications for bored pile foundations in seismic zones, particularly the dominance of shear force amplification under earthquake loading, providing essential data for optimizing foundation design in high-rise structures.
