Subject: Worked example of a tower crane foundation design, including calculation methodology and a reference link to supporting standards/data.
Sliding resistance:
( R_slide = (V_d) \times \tan(2/3 \phi') + c' \cdot A_base )
( V_d ) (ULS, with wind) = ( 1.35 \times 950 + 1.0 \times 1134 = 2,416 , kN )
( \tan(2/3 \times 30°) = \tan(20°) = 0.364 )
Friction term = ( 2416 \times 0.364 = 879 , kN )
Cohesion term = ( 5 \times 30.25 = 151 , kN )
Total resistance = ( 879 + 151 = 1,030 , kN ) tower crane foundation design calculation example link
Driving force ( H_d = 1.5 \times 75 = 112.5 , kN )
( FOS_slide = 1030 / 112.5 = 9.2 \gg 1.5 ) → OK. Project Number: TCF-2026-001 Date: April 19, 2026 Author:
We’ve prepared a comprehensive Excel spreadsheet that automates all checks above and includes: Sliding resistance: ( R_slide = (V_d) \times \tan(2/3
