Tower Crane Foundation Design Xls ((free)) -

The spreadsheet calculates the combined loads on the foundation:

For piled foundations, the spreadsheet must calculate:

Inputs are typically derived from the crane manufacturer’s technical manual:

Most common for sites with good soil capacity. Tower Crane Foundation Design Xls

Safety Factor against Overturning = Resisting Moment / Overturning Moment ≥ 1.5 (typical)

Here is an example of what the Excel spreadsheet might look like:

For the next decade, the Excel spreadsheet will remain the lingua franca of crane foundation engineering. It is on every site engineer’s laptop, does not require an internet connection, and is trusted by building inspectors worldwide. The spreadsheet calculates the combined loads on the

– Prevent accidental overwriting of critical formulas while leaving input cells editable.

Your Excel spreadsheet must input these four values directly from the manufacturer data sheet: Total downward weight. Horizontal Shear Force ( ): Lateral force from wind and movement. Overturning Moment ( ): The rotational force trying to tip the crane over. Torsional Moment ( ): The twisting force from slewing braking. 2. Choosing the Right Foundation Type

(Prevents the mast from punching cleanly through the footing). Overturning Moment ( ): The rotational force trying

Checks the risk of the crane mast punching through the concrete slab at a distance of from the perimeter of the anchor base.

Allows engineers to quickly optimize the footing thickness, reinforcement steel, and pile configuration.
