Tower Crane Foundation Design Calculation Example -

Determine the allowable bearing capacity ($q_\textall$) of the soil from geotechnical reports. This dictates the size of the footing required to prevent the soil from shearing or settling excessively.

L = B = 5.8 m, h = 1.5 m W_f = 5.8 × 5.8 × 1.5 × 25 = 1,261.5 kN M_R = (850 + 1,261.5) × (5.8 / 2) = 2,111.5 × 2.9 = 6,123.35 kNm F.S. = 6,123.35 / 4,500 = 1.36 → Still below 1.5. Tower Crane Foundation Design Calculation Example

Get a fresh geotechnical report for the specific spot. Check Eccentricity: Try to keep to ensure the full footing stays in contact with the soil. Factor of Safety: Always aim for or higher for overturning. = 6,123

Selection depends on soil conditions, space, and economic factors: Types of Tower Crane Foundations Factor of Safety: Always aim for or higher for overturning
