Tower Crane Foundation Design: Calculations and Examples Designing a tower crane foundation is a critical temporary works task that ensures the stability of the crane under maximum reactions and moments. The foundation must be designed as a freestanding structure to ensure it independently resists all vertical loads, horizontal shears, and overturning moments. Common Foundation Types
Horizontal Loads: Wind pressure acting on the crane structure and the load, as well as slewing (rotating) forces. tower crane foundation design calculation example link
Foundation geometry (trial size):
Using simplified method (beam strip width 1 m):
Average pressure ( q ) under ULS ≈ 230 kPa.
Cantilever length = ( (5.5 - 0.8)/2 = 2.35 , m )
Moment per meter width:
( M_Ed = \fracq \cdot L_c^22 = \frac230 \times 2.35^22 = 635 , kNm/m ) as well as slewing (rotating) forces.
