Tower Crane Foundation Design Calculation Example Link 'link' -

Introduction Tower cranes are the backbone of high-rise construction. However, a tower crane is only as reliable as the ground it stands on. A catastrophic foundation failure can lead to loss of equipment, project delays, injuries, or fatalities. Unlike standard building foundations, tower crane foundations are subjected to extreme overturning moments, torque, and horizontal forces.

Soil pressure at face (linear distribution): q_at_face = q_min + (q_max - q_min) × (distance from edge). tower crane foundation design calculation example link

But for simplicity, use factored ULS load: M_Ed = (q_average * overhang²) / 2 ... In detailed design, we use trapezoidal distribution. Introduction Tower cranes are the backbone of high-rise

Lever arm (distance between two bolt rows) = 1 m. Tension force per bolt pair = 4,500 / 1 = 4,500 kN / pair. Per bolt = 2,250 kN. This is too high – thus, increase bolt size or embedment. In detailed design, we use trapezoidal distribution
