Using the loads and soil properties, the foundation size and depth can be determined:
Mtotal=Mmax+(H×D)cap M sub t o t a l end-sub equals cap M sub m a x end-sub plus open paren cap H cross cap D close paren

Assuming a square foundation with a side length of 2 meters:
(Two-way Shear): Punching shear is a critical failure mode where the concentrated load from the crane's steel baseplate pushes through the concrete slab. The foundation's thickness is designed to resist this. The shear strength of the concrete ( Vc ) must be greater than the applied shear force ( Vu ) from the crane's column. This calculation uses the concrete's tensile strength ( ft ) and the perimeter of the load area ( u_m ).

Wf=6.5 m×6.5 m×1.4 m×25 kN/m3=1,478.75 kNcap W sub f equals 6.5 m cross 6.5 m cross 1.4 m cross 25 kN/m cubed equals 1 comma 478.75 kN
A tower crane foundation is a critical component of the crane's overall design. The foundation must be able to support the weight of the crane, the loads it will be lifting, and any external forces such as wind and seismic activity. A poorly designed foundation can lead to a range of problems, including:
