). For brevity, assume an ultimate design pressure distribution yields a maximum factored soil pressure Flexural Reinforcement (Bending Moment)
New self-weight = 7×7×1.5×25 = 1,837.5 kN Total V = 850 + 1,837.5 = 2,687.5 kN
(Note: For a simplified stability check, we often use unfactored characteristic loads to check overturning, and factored loads for bearing pressure checks.) tower crane foundation design calculation example link

We check if the eccentricity falls within the middle third of the footing base to prevent uplift (where the footing lifts off the soil):
Area = (50 + 10) / 150 = 0.4 m²
Design moment at column face (using factored loads: γ = 1.5 typical for crane loads in ULS):
