Tower Crane Foundation Design Calculation Example Link Jun 2026

for extreme out-of-service conditions (depending on local codes). Step 4: Concrete Structural Design (Ultimate Limit State)

Overturning moment M = 3,200 kNm Horizontal force H = 180 kN → effective moment at base: M_eff = M + H × h = 3,200 + 180 × 1.2 =

A factor of 1.61 exceeds the required 1.5, confirming the foundation is stable against overturning. tower crane foundation design calculation example link

Since the calculated Pmax (202.0 kPa) is , the soil bearing capacity is adequate for this load case.

$$ G = B^2 \times h \times \gamma_c = 6.0^2 \times 1.5 \times 24 = 1296\ \textkN $$ For this example, consider a 36 m high

Manufacturers provide service loads (unfactored characteristic loads). For this example, consider a 36 m high tower crane with a 70 m boom:

Verify the concrete thickness is sufficient to prevent the crane legs from "punching" through the slab. 3. Critical Design Considerations
