Tower Crane Foundation Design Calculation Example Link [updated] File

$0.933 \text m > 0.833 \text m$ FAIL. The eccentricity is outside the middle third. This implies part of the foundation is lifting off the ground (tension), which is unacceptable for a gravity base on soil.

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 tower crane foundation design calculation example link
